DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 1 Enhancements: R5.0 is the most significant "face lift" the program has ever received. The number of fades and drawing algorithms have been greatly expanded. A truly fresh interpretation of the DAZZLE vision. Configuration menu sets number of images and pause time in Auto mode. "/W" command line option for easier use with Windows (a windows driver is a separate product). Keyboard LED's indicate program state and progress. The "/Z" option creates DAZZLE.DOC User's Manual. Enhanced interactive control. 2. INTRODUCTION DAZZLE is an award winning self directing color image generator for DOS and Windows computers with EGA or VGA compatible color displays and adapters. Performance art for the eyes. A source of beauty; sometimes subtle, sometimes vibrant, always changing. The image engine has numerous primary image drawing algorithms, most of which have at least two styles of presentation, many of which have multiple internal drawing variations. There is an assortment of fades, including split screens and pans, used by the imaging system for greater diversity of presentation. The entire color range of the detected video system is utilized for maximum variety and visual stimulation. When the "Semi-Automatic" mode of DAZZLE is active, the user can play the program from the keyboard. Specifically selecting each pattern to draw, or letting the program select the pattern randomly. The selected pattern is generated for as long as the user holds the draw key. There are no limits on the mixing of image patterns. The user can then invoke a specific fade effect, or let the program select an effect randomly. The types of displays that can be generated in this fashion are far more varied, and personal, than anything that "Auto" mode ever produces. There is a configuration menu that allows the customization of DAZZLE image generation. It also allows the selective disabling of various fades. This configuration information can be written to an editable text file, and either loaded again from the menu or loaded automatically at program invocation by specifying the file name on the DAZZLE command line. An on-line HELP text window system is included in DAZZLE. In the self generating "Auto" mode the primary image algorithms are mixed randomly on the screen. An adjustable number of images are overlaid at a time, producing a very large assortment of possible displays. Each display remains for a while to be appreciated, then the screen is cleared via a fade algorithm, and another set of patterns is presented. Mathematically speaking, an exact pattern match might not occur for many weeks of continuous operation. Human perception is far less exacting and will discern repetition well ahead of these extremes, but the general effect is impressive and frequently surprising. Note that the starting patterns of the program will be different each time it is executed. If the program seems predictable, exit it and start it over again. DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 2 "PsL News" (713-524-6394) described DAZZLE as: ...the best kaleidoscope program we've seen yet. The beautiful use of colors, enhanced even further by the use of fading in and out, is, for want of a better word, awesome. DAZZLE has received many other good press reviews, and has been awarded "Best New Graphics Program for 1990" (December 90 PsL News). There have since been complimentary reports too numerous to repeat here, my thanks to all who have been so supportive. DAZZLE can be used in a variety of ways. At the office it keeps the screen from being burned by constant display of an unchanging prompt. Simply start the program when leaving your desk or answering the phone or otherwise diverted. One option is to start DAZZLE from a keyboard locking program so that unauthorized access is prevented on your unattended computer until you return. Additional programs are available from MicroTronics that provide self-starting DOS and Windows Screen Saver capability, and optional password protection. In reception areas, at trade shows, in showrooms, in waiting rooms, in schools, in display windows, and other events where the desire is to attract attention; use a faster cycling mode of DAZZLE to peak curiosity and draw visitors to your area. A program called DAZLOGO has been released for customers that want their logo or other custom images integrated into DAZZLE for regular presentation. DAZZLE also can be invoked from within your presentation software (see the "/S" and "/B" command line options) for an extra touch of pizzazz (selling or distributing any program that includes DAZZLE requires an active OEM agreement with MicroTronics). DAZZLE can be used to aid relaxation. In its slower cycling VGA modes (where this program REALLY shines) it is often soothing and helps one to shift conscious attention from the cares of the day. Various university and medical studies conducted on volunteers watching DAZZLE document a reduction of blood-pressure, general relaxation, and heightened alpha states in the brain. When overwhelmed with problems or pressures, it is often true that shifting one's focus from an immediate concern allows the objectivity needed to enhance decision making and settle the nerves. DAZZLE is a performing art realization on a computer platform. Used with your favorite music DAZZLE can be highly entertaining and regenerating. In its self-directing play mode it is great "living" mobile art. Capture stills, record it on your VCR, use the images as backgrounds for your slide presentations, or play it live with your band (note the Royalty section below). Applications are boundless. 3. SHAREWARE Shareware is a brave concept in software marketing that allows you to "try before you buy." Shareware authors retain all rights under their copyright, but allow free distribution of their programs. Distributors of shareware--including on-line BBS and catalog outlets--usually do not charge for the shareware software itself. The distributors are charging for their own services in providing access to their resources. Registration payment DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 3 directly to the author entitles the user to additional services, information, and newer products. It is a great deal for users, authors, and distributors alike. Please support this honor system marketing technique so that more great programs of increasingly professional quality can reasonably be provided via this system. Copyright laws apply to both shareware and commercial software, and the copyright holder retains all rights, with a few specific exceptions clearly stated by the author. Shareware authors are accomplished programmers, just like commercial authors, and the programs are of comparable quality--in both cases there are good programs and bad ones! The main difference is in the method of distribution. The shareware author specifically grants the right to copy and distribute the software to all, except that MicroTronics requires that written permission be acquired before a commercial disk vendor may copy or distribute our products. Shareware is a distribution method, not a type of software. You should find software that suits your needs and budget, whether it's commercial or shareware. The shareware system makes fitting your needs easier, because you can try before you buy. And because the overhead is low, prices are low also. Shareware has the ultimate money-back guarantee--if you don't use the product, you don't pay for it. You are encouraged to pass a copy of DAZZLE along to your friends for evaluation, but please do not give it away altered or as part of another system. Please encourage them to register their copy if they find that they can use it. 3.1. Usage Limitation Please note that this program is NOT FREE. You are entitled to use it for evaluation over a short time (not more than 10 days) to determine if it functions adequately for your needs, after which time a registration fee paid directly to MicroTronics is required by copyright law, and greatly appreciated by all of us. Any distribution or on-line fee paid by you to copy DAZZLE is (usually) not forwarded to MicroTronics by the distributor, and therefore would not constitute payment of a registration fee. The images generated by this program are subject to usage limits and royalty fees, refer to the Royalties section for additional details. 3.2. Revision Control MicroTronics is NOT responsible for revision control of DAZZLE through any source other than direct mailings from our office. If you request a copy from any other source please be certain of the revision level that you are acquiring, and that it contains all related files and documentation. Your registration fee for DAZZLE entitles you to one disk copy update of DAZZLE from us within the first year--at your option. It is assumed that all payments are registrations of existing copies, so disk are not automatically mailed unless the request for "order" or "update disk" is clearly identified in the letter. Many users prefer to retain their update option until the next newer release is available. PLEASE specify your floppy disk format when writing. Once you have received your update disk, DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 4 additional disk updates are available at a reduced fee. Names on our PRIVATE mailing list are never shared with others, and will be maintained for at least 1 year from last contact unless materials are returned without forwarding address. 3.3. Current registration fee and discounts The registration fee for this version of DAZZLE is $15 ($20US for customers outside the continental U.S.A. please). For those that wish to buy multiple registrations of the unmodified shareware product the following discounts are currently allowed: Copies 1 through 3 Registration cost $15 each ($20US foreign) Copies 4 through 8 Additional cost $12 each ($17US foreign) Copies 9 or more Additional cost $7 each ($12US foreign) Thus 12 copies would cost $133.00 (3x$15 + 5x$12 + 4x$7). Discounts may be discontinued without prior notice. Multiple registrations make for a great gift idea to your computer using friends, and are wonderful around the office. This pricing is for independent registrations of multiple program copies. MicroTronics will provide a disk and documentation for each copy thus registered, and put the recipient of each copy on our mailing list. A single registration fee will license one copy for use on any one computer at any one time. You must treat this software just like a book. An example is that this software may be used by any number of people and may be freely moved from one computer location to another, so long as there is no possibility of it being used at one location while it's being used at another. Just as a book cannot be read by two different persons at the same time. 3.4. Site Licenses Also available are MULTI-COPY or SITE LICENSES. The licensee receives one "master" copy of the program and all related documentation, additional master copies of disk and/or documentation available for an extra charge. These may be copied by the licensee for multiple users at the designated location (site) up to the number of licensed copies. The current offer is that $15 is paid for the master copy supplied from us, and you pay $5 for each additional copy that you make (subject to the terms of the Site License agreement). The number of authorized copies can be automatically extended by simply submitting the additional funds with a letter referencing the original site license. 3.5. OEM/VAR Licenses Multi-copy OEM/VAR licenses are available at a reduced cost for developers that wish to incorporate MicroTronics programs into their own product for resale. There is also an open-ended license that allows DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 5 unlimited copies to be distributed for a single one-time fee. These licenses include priority telephone support and free extended period product upgrades for the licensee. 3.6. Future Products Self activating DOS and Windows Screen Saver drivers, and a full computer security version of MT-DAZE, are available from MicroTronics. These are retail enhancements to the shareware versions of the DAZZLE family of programs. A derivative non-shareware product called DAZLOGO allows commercial clients to incorporate their own logo or other artwork for regular presentation by the DAZZLE display for trade shows, waiting rooms, promotional gifts, and other uses. Write us for details. Another derivative product soon to be released is DAZTUTOR. This allows users to experience a revolutionary Psycho-Ergonomic(TM) stress-less computer aided memorization technique. Commit information to memory during a high-alpha state of relaxation without the duress and distraction associated with other memorization environments. By the summer of 1992, MicroTronics will make available DAZZLE merchandise of a broad variety, including: Music Videos, Shirts, Mugs, Cards, Prints, Stick'EMs, and such. The rapid success of DAZZLE has prompted us to expand our resources and dedication to this marketplace. We have a number of interesting projects in the works to reward registered users for their faithfulness. 3.7. Royalties All commercial rights to this program are retained by the author. Revenue or any other form of remuneration resulting from images captured or photographed or in any way derived from DAZZLE, or any MicroTronics programs, are subject to usage limitations, royalties, fee's, or other claims by the author.

Distribution Limitation Anyone distributing DAZZLE for any kind of remuneration must first contact MicroTronics for authorization, use of the Distribution Authorization form below is recommended. This authorization will be automatically granted to distributors recognized by the (ASP) as adhering to its guidelines for shareware distributors, and such distributors may begin offering DAZZLE immediately (however MicroTronics must still be advised). 4. COMMAND LINE OPTIONS A number of options that control the action of the DAZZLE family of programs can be specified on the command line when the program is invoked, or can be encoded into a batch file for easy activation. 4.1. Main Options Menu When you enter the command "DAZZLE -?" at the DOS prompt you will be presented with the following display. Usage: DAZZLE -options inputfile -$ Display order information. -2 2 part palette update to fix flickering screens (slower). -a Alternate (faster) color cycling speed. -b Bashful, no closing credits & any key aborts. -c Compatible mode, use BIOS for better portability. -d Delay, slow down drawing for faster PC's. "-d=xxxx" delay xxxx units. -i Insecure, no antiviral checking. -m Mad (fastest) color cycling speed. -n No retract of hard disk heads. -q Quiet, no tones (no effect on warning beeps). -s Show mode, quick single image. "-s=xxxx" Show mode, duration xxxx seconds. -w Window environment, no messages & changes some defaults. -x XT compatible, inferior but works. -z Create DAZZLE.DOC file on current disk path! During the display the TAB key will FREEZE the display till SPACE is pressed. F1 activates on-line help during the program. F2 provides a configuration menu. ESCAPE terminates the program. DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 7 4.2. Additional Options Menu When you press a key at the "Press Any Key" prompt you will be presented with the following display. If an "inputfile" is not specified, the program will try to locate and load MTDAZZLE.DZL from the current path. To prevent this load specify an inputfile name of "*" Additional Options -e EGA operation mode forced. -h Hide EGA border. -k Keyboard typematic unchanged. -t Tall video aspect ratio mode. ***** limited use command line options ***** -+ Ignore TARGA+64, even if present. -! Monitor Screen Saver driver interface. -4 Restrict the EGA mode to only 4 random colors. -f Fixed colors instead of randomized. -v VGA operation mode forced. 4.3. Specifying Options The DAZZLE program accepts any combination of options on the initial command line that affect its mode of operation. The options can be preceded with either the "/" (slash) character or the "-" (minus) character. If you use the SwitchChar feature of MSDOS, the "/" (slash) option marker character can be changed to any other key. At least one space must exist between the DAZZLE command and the first option. For example: "DAZZLE -FN" instructs DAZZLE to execute with Fixed colors and No retract of the hard disk drive heads. The options are not case sensitive-upper and lower case letters are treated identically. The options can be concatenated into a single string (like: -FN), or can be entered separately (like: -F -N), the effect is the same. The optional inputfile can be specified anywhere on the command line. For example: "DAZZLE -I DAZZLE.DZL" has the same effect as "DAZZLE DAZZLE.DZL -I", which is to tell DAZZLE to startup in the insecure mode, and to load configuration file DAZZLE.DZL prior to starting the image generation process. Note that DAZZLE will automatically attempt to locate and load a configuration file named MTDAZZLE.DZL unless explicitly instructed otherwise with the "*" or "-*" command line options. The effects of each option are detailed below. 4.4. Compatibility Options Some of the options for DAZZLE are specifically related to increasing portability of the program to various computers and displays. The "2", "c", "d", "e", "k", "n", "v", and "x" options default to the most desirable modes, but can be controlled by the user. VGA users also should refer to the "t" option for details. DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 8 4.4.1. /2 = 2 part palette update. Normally the entire color palette is updated at one time for each tick of the color cycling clock. If the CPU clock speed or the VGA palette register update rate is too slow, the upper part, or perhaps all of the display, will flicker badly during the display. To determine if this is due to palette updates, press and hold the "-" (minus) key during the running graphics display until it beeps (this is the slowest cycling clock rate). If the display flickers only when the color changes, then palette update speed is a problem. Using the "2" option splits the VGA palette update request into two almost equal groups that are handled sequentially. This should remove, or at least significantly reduce, cycling induced flicker. This option should not be used if not needed, as it slows the entire display generation process. This option affects operation with VGA adapters only, since they allow longer 256 color palettes. Short 16 color palettes for EGA's are never divided into two separate updates. 4.4.2. /C = COMPATIBLE mode, use BIOS. Normally DAZZLE bypasses the video adapters BIOS code for maximum speed in color palette cycling. However, some rare adapters may have problems with this mode of operation. To cause DAZZLE to use the provided BIOS the "C" option can be used. If your display flickers or distorts, or the color fails to cycle smoothly during the display, then try this option to determine if it corrects the problem. This option reduces program performance speed and should not be used if not needed. 4.4.3. /D = Delay, slow down drawing for faster PC's. "-d=xxxx" delay xxxx units. This option serves both artistic and compatibility purposes. On faster computers the DAZZLE drawing algorithms can be too fast to appreciate as an evolving image. If the computer is too fast, or if you simply desire to induce a slower drawing speed for purely aesthetic reasons, this option can be used to delay the drawing process. If used simply as "/D", without specifying any delay units, the program will use a default delay amount. To adjust the amount of delay a specific value can be provided after the "=" (equal) character. There is no exact relationship of the delay unit value and the impact on the drawing speed, it must be experimentally determined on each computer. The larger the number, the slower the drawing (TARGA+64 users note: this option works in reverse on this system, larger unit numbers produce faster drawing). The delay unit value ranges from 1 (minimum) to 8191(maximum), and can be entered without leading zero's. There must be no spaces or tabs between the "D", the "=", and the numbers for the delay units. This option can be concatenated with other non-numeric options. Thus "/AD=250W" is a legal command option string. 4.4.4. /E = EGA operation mode forced. Normally DAZZLE will automatically detect the video adapter hardware attached and adjust itself to use either the EGA or the VGA mode. This "/E" option allows VGA users to select and view the EGA mode of operation, which is 640x350x16 in format. As of revision 4.0 this option, like the "/V" option, will prevent DAZZLE from aborting if it thinks that it has detected an unacceptable video controller/monitor combination, though it will still DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 9 give its usual error messages during startup. Refer to the "/V" option below for more information. 4.4.5. /K = Keyboard typematic unchanged. Revision 4.1a contains enhancements to make the program largely immune to some "keyboard acceleration" utilities that exist. These utilities cause the self-repeating "typematic" function of the keyboard to function far more rapidly. They come in two flavors: * Those that tell the keyboard to send keys more often. * Those that trick DOS into thinking that more keys arrive than actually are sent by the keyboard. Without specifying this command line option, DAZZLE will set the "typematic" rate of the keyboard to it's minimum value for best program performance. When DAZZLE terminates it puts the "typematic" speed back to a value typical of most DOS defaults, unfortunately I am not aware of a way to test the setting before changing it. Those that use a keyboard speed-up utility that stops having an effect after DAZZLE has been executed have the first type of such a utility. If you want the keys back to their quicker speed you can re-execute your speed-up command. If you find this unacceptable then use this command line option to force DAZZLE to keep from changing the "typematic" rate of the keyboard. The "/S" , "/W", and the "/B" options automatically disable changing of the typematic rate. 4.4.6. /N = NO retract of hard disk heads. Since the DAZZLE display is often allowed to run for hours, the hard disk heads are normally parked into a safe power-down position (as determined by the BIOS in your specific computer) as a precaution in case electrical power is lost, or the computer powered down while DAZZLE is active. This process has no effect on the image generation performance of DAZZLE, but if your drive controller is highly nonstandard it might cause DAZZLE to fail to start. Some disk drives make a really nasty sound when they are next accessed after they have been parked. While this is not an error, nor technically a cause for concern, it sure can upset someone not aware of what is happening. The user can issue this option to prevent any attempt to park the hard disk heads. If you have any reason to doubt the safety of using the head parking feature with your computer/drive combination then please always use this command line option. 4.4.7. /V = VGA operation mode forced. Normally DAZZLE will automatically detect the video adapter hardware attached and adjust itself to use either the EGA or the VGA mode. This option generally SHOULD NOT BE NECESSARY, OR USED. It should be unable to cause any damage, but is intended for rare compatibility conflicts where the startup code in DAZZLE falsely rejects the video controller/monitor combination as unacceptable. This option, like the "/E" option, will allow the error messages to be reported (so that you can write us of the problem), but will prevent the program from aborting itself. If the controller/monitor is really VGA compatible, or really EGA compatible if using the "/E" option, then normal image generation should be observed. Unlike the "/E" option, this option lacks artistic usage or impact. The VGA mode uses all 256 color palette registers for a far more subtle and interesting series of displays. The default VGA mode of DAZZLE uses a DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 10 specially enhanced 320x400x256 mode that is not properly captured by many commercial products. The VGA modes require no more than 256kB of video memory. 4.4.8. /X = XT compatible mode, inferior but works. This option allows DAZZLE to execute on 8088 or 8086 based PC/XT type computers with EGA or VGA adapters and color displays. This option will be automatically initiated if the 808x style CPU is detected at program startup, but specifying the command line option avoids the warning message. The EGA performance on XT computers seems acceptable, but the VGA mode may be noticeably inferior to the performance of an 80x86 based computer. The faster the CPU clock the better the overall performance and fluidity of DAZZLE. 4.5. Artistic Options These options adjust the image generating algorithms used by the program. They are largely artistic in nature but allow customizing the presentation to various environments and requirements. 4.5.1. /4 = Restrict the EGA mode to 4 colors. The default EGA mode will use the full complement of available colors for the display. Using this option restricts the display to only 4 simultaneous colors at one time. This is used when the output from DAZZLE will be directed to another system that does not support more than 4 colors (like automated weaving or embossing machines. Note Royalty section above.). 4.5.2. /A = ALTERNATE (faster) color cycling speed. The default color cycling mode is the slowest, with the most subtle shadings and transitions. This option increases the cycling rate used in shaping the palette contents. This effect is distinct from, but can complement, the "+" and "-" keys that can be used while the program is active. 4.5.3. /F = FIXED colors instead of randomized. Normally DAZZLE will randomize the color palette registers between each screen erase before starting the next image generation. This allows all the possible colors (up to a quarter million on VGA) to be used by the program. This option forces the palette to an identical state at all times. 4.5.4. /H = Hide EGA border. Some folks find the colored border on the EGA display distracting, and some displays do not perform retrace masking properly. This option will cause the border color in EGA modes to be forced to black at all times. 4.5.5. /M = MAD (fastest) color cycling speed. This option not only greatly accelerates the color palette contents rotation, but it also increases the number of image primitives that can be displayed in "Auto" mode at one time before the screen is erased. The effect is a far busier screen, a more intense visual experience. This is particularly suited to attention-getting in showrooms and other public displays, whereas the default mode is more practical for personal meditation and relaxation. DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 11 4.5.6. /S = SHOW mode, quick single image. "-s=xxxx" Show mode, duration xxxx seconds. The "/S" option gives a single panel of images and then terminates automatically. This is most useful when DAZZLE is to be executed from within other programs or batch files. The image displayed is different each time. The "/S=xxxx" option allows DAZZLE to execute for a specified length of time, after which it will terminate at the end of the next fade. The duration value ranges from 1 (minimum) to 3600(maximum), and can be entered without leading zero's. There must be no spaces or tabs between the "S", the "=", and the numbers for the duration. This option can be concatenated with other non-numeric options. Thus "/AS=250W" is a legal command option string. 4.5.7. /T = TALL video aspect ratio mode. Normally the EGA mode of DAZZLE uses a 16 color 640x350 resolution display with a modified aspect ratio (screen is mapped as if it had 640x700 resolution). The default VGA mode uses 256 color 320x400 resolution. The "/T" option causes the program to use the standard BIOS supported screen resolution and aspect ratio in generating all images. The effect is somewhat faster image generation, but with a noticeably tall aspect ratio. As of revision 4.0 this option is functional with the VGA display mode, and causes it to use the BIOS supported 320x200 video mode. Note that due to VGA hardware limitations, using this option will prevent the display of "dual page" effects (where a screen composed of a different image than the one being displayed is "panned" or "scrolled" onto the visible display area). 4.6. Other Options 4.6.1. /$ = Display order information. Issuing this option when invoking DAZZLE will cause the program to output a convenient order form that can be quickly completed and sent to MicroTronics for product orders, information request, and shareware registration. To send this form directly to a printer use the MSDOS output redirection character ">" (greater-than) to specify the destination. For example, if you have a printer that can accept standard ASCII text on your computer port PRN:, then the command to use would be: DAZZLE -$ > PRN: Complete the form and mail it to the indicated address. Enclose any indicated funds in U.S.Dollar instruments, payable to MicroTronics. 4.6.2. /B = Bashful, no closing credits. DAZZLE will identify itself, including its revision level, when the program is started. The BASHFUL option will prevent closing credits when the program terminates (similar to the SHOW option), and additionally prevents DAZZLE from clearing the type ahead keyboard buffer when it exits. This allows usage of DAZZLE in a more classical "Screen Saver" mode, since whatever key is pressed to exit is not lost. This mode disables ALL key DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 12 interpretation of DAZZLE. Even the "+" and the "-" keys will cause DAZZLE to terminate. The shareware version of DAZZLE does not initiate itself in a "Screen Saver" fashion under DOS or Windows, this flag is used by the retail Screen Saver drivers from MicroTronics. This mode blocks the use of the keyboard LED's to indicate the state condition of the executing DAZZLE program. DAZZLE has been successfully used within MS/Windows (copyright Microsoft), but use of this option will prevent window selection keystrokes. Use of the command line option "/W" was added in R4.2 for the windows environment as detailed below. 4.6.3. /I = Insecure, no antiviral checking. Before starting the image display process DAZZLE will normally perform a test on the disk copy of itself in an attempt to assure that no unauthorized modifications ("hacks") have been made to the program after it was distributed from MicroTronics. This is a safety feature added for YOUR protection! Please note that this is not a system wide scan for virus infection-only the current disk copy of the DAZZLE.EXE file is checked, nor is the self-check completely exhaustive. Once you have used your copy of DAZZLE, after it has passed its antiviral test and you no longer wish to endure the delay at every invocation for this testing, you can use this command line option to bypass this safety feature. IF YOUR COPY OF DAZZLE FAILS THIS TEST, PLEASE NEVER USE THIS OPTION! INSTEAD WRITE TO US, AND TO THE SUPPLIER THAT GAVE YOU THE BAD COPY, AND LET US KNOW! A clean copy can be in your hands in a very short time, and might save your entire software investment (NOTE: MicroTronics only supplies disk to registered users). 4.6.4. /Q = Quiet, no tones (no effect on beeps). This option will block the tones that DAZZLE emits at various points in its operations. But warning beeps are generally not restricted. As of revision 4.1, DAZZLE uses programmed tones for most alerts and signals that it issues. These tones are of short duration, and change pitch depending on the condition being signaled. With the increase in operational options these tones are very helpful in determining the state the program is in. The one place where these tones are superfluous is the tiny tune in the closing credits, but this tune can be aborted with any keypress. 4.6.5. /W = Window environment, changes defaults. This option was added to simplify use of DAZZLE within MS/Windows environments. It prevents the startup antiviral check (please see the "/I" option for a discussion of the risk involved), disk head parking, and all startup messages. This mode blocks the use of the keyboard LED's to indicate the state condition of the executing DAZZLE program. It allows normal "switch" key commands to Windows for task switching. DAZZLE will still show the closing credits graphic image, but not the closing text messages. 4.6.6. /Z = Create DAZZLE.DOC file DAZZLE keeps the entire Users Manual within itself in an efficient manner that has minimal impact on total usage of the program. By specifying this option DAZZLE will create a new DAZZLE.DOC Users Manual file on your current default disk directory, which you can then print. Note that this file is formatted for generic text printers. DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 13 4.6.7. /+ = Ignore TARGA+64, even if present. The TARGA+64 card from Truevision can be used with a special limited- availability non-shareware version of DAZZLE to produce high quality NTSC video images. This option allows the special TARGA compatible version of the program to ignore the video card so that it will use the computers normal VGA display. 4.6.8. /! = Monitor Screen Saver driver interface. The retail versions of MT-DAZE and related products allow execution as a self activating Screen Saver under both DOS and Windows3.x. This option allows the retail version of the program to monitor the Screen Saver driver interface so that it performs normally in that environment, which is the default mode invoked by DAZTSR. 4.7. Specifying the INPUTFILE DAZZLE can accept the optional specification of an input file on the command line. This file must contain a text script that is consistent with the program's language specification. The specification of a path as well as a filename is acceptable. Be sure to separate the file name from options with at least one space. As of R5.0, DAZZLE will automatically attempt to locate and load a configuration file named MTDAZZLE.DZL unless explicitly instructed otherwise with the "*" or "-*" command line options. 5. ON-LINE HELP DAZZLE supports an on-line help menu system. You may press the "F1" function key to activate the help subsystem. This system is intentionally limited in size and scope to keep the program from growing too large, but it offers useful summaries of the newest and most pertinent features of DAZZLE. The graphics screen that was being displayed when help is activated is erased when help is exited. 5.1. Cursor Keys within HELP When within the help subsystem DAZZLE recognizes the various standard cursor keys. The "HOME" key jumps to the first page of help text. The "END" key jumps to the last page of help text. The "PgDn" key advances to the next page of help text, the "PgUp" returns to the previous page. The arrow keys also can be used. Note that the bottom right of the text window shows what page movement keys are valid at that point. 5.2. Exiting HELP The text menu subsystems, including the help system, can be exited by pressing the same key that invokes that subsystem. Thus to exit help press the "F1" key again. 6. LED Indications during DAZZLE DAZZLE family of programs control the lighting of the Num Lock, Cap Lock, and Scroll Lock LED's (Light Emitting Diodes) on the keyboard to DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 14 indicate to the user the state of the program as it moves through the various conditions or "states" in normal operation. These LED's (or lights) can be on, off, or blink; each represents a different condition as detailed below. Note that use of the "/W" or the "/B" command line options prevent the DAZZLE program from changing the keyboard LED indicators. 6.1. Scroll Lock LED This light indicates 1 of 3 possible conditions for the program. 1) When off, the program is not in any pause state, something is actively being computed or displayed. 2) When blinking, the program is in an active countdown of a normal pause delay. When the delay expires the program will proceed to the next action without any need for user intervention. 3) When on, the program is halted in a pause state, and will not proceed until the user takes some action. This can be induced by pressing either the "TAB" key or the "H" fade key. Refer to the details elsewhere for these specific keys to understand how to release the program from this state. This condition also occurs when any text menu is on the display, use the specified menu exit command to restore normal program execution. 6.2. Num Lock LED This light indicates that the program is either computing or displaying a "Pan/Scroll Fade" process. If no activity is visible on the screen then the program is building a new image on the "hidden" display so that it can be moved onto the active or "visible" display area. Refer to the "P" fade key for additional details. 6.3. Cap Lock LED This light indicates that the program is computing a new VGA color palette to use on the active display. The duration of this period is directly dependent on the math speed of your computer. This indication was added to inform users when their program seems halted that valid computations are progressing unseen within the system. Refer to the "Shift-F10" key description for additional details. 7. PRIMARY DAZZLE MODES DAZZLE has two primary modes of operation. The original "Automatic" (a.k.a. "Auto") mode, which is fully self generating; and a new "Semi-Automatic" (a.k.a. "Semi-Auto") mode, which allows interactive control of the image generation process. Some keys are only effective in the "Semi-Automatic" mode, others are active at all times. 7.1. Selecting Modes Selection between these two modes is done by pressing the "ALT" (Alternate) key and the "F9" function key. This combination is referred to as "Alt-F9". At program startup DAZZLE is always in "Auto" mode. DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 15 To enter "Semi-Auto" mode press "Alt-F9". There is a short high pitched tone. The display is cleared. The palette is reinitialized to a new setting (this may take a few seconds on a slow VGA machine). Then a short multi-tone chirp is emitted to indicate that "Semi-Auto" is ready for image drawing commands. To return to "Auto" mode press "Alt-F9". There is a short lower pitched tone. The display is cleared. The palette is reinitialized to a new setting. Then the self generating engine begins creating random image displays. 8. KEYS ACTIVE IN ALL MODES Some key commands that DAZZLE recognizes are active regardless of the current display mode. The meaning of some keys change slightly depending on the current display mode. 8.1. ESCAPE : Program Termination "The first and most important thing to learn about any program is how to get out of it." This key will do the job for you regardless of where you are in the program, just keep banging it till you get back to the DOS prompt. Note that when not in the various text menu screens, that "ENTER" also will terminate the program. 8.2. TAB : Freeze Image The "TAB" key can be pressed at any time when not in a text menu to "freeze" the current graphics image display. Once pressed, DAZZLE will remain in "freeze" mode until the "SPACE" key is pressed (the "n" key will also work). While in "freeze" mode, the "TAB" can be repeatedly pressed to toggle between color-cycling and color-static modes. The "Shift-F10" key can be used to change the palette of an image in "freeze" mode. This is most useful in stabilizing a specific display for image capture. Even an image in the midst of a fade or pan can be put into "freeze" mode. This key is also active in the "Semi-Automatic" mode, though here its usefulness is limited to halting a fade in mid-execution. The Scroll Lock LED on the keyboard will be continuously lighted to indicate that "freeze" is active. Refer to the section on Scroll Lock LED above for more details. 8.3. F5 : Dump Screen Image to Disk File Pressing the "F5" function key converts the display memory into an industry standard PCX disk image file. The program will name the file "DAZ_xxxx.PCX", where xxxx is replaced with a number from 0000 to 9999, depending on what filenames already exist on the current disk path. The image format will match the current video mode of the program. The program will resume normal display after the file is completely written. If a "Pan/Scroll" fade is in effect when "F5" is pressed the "current" display will assume full screen position for the duration of the file creation, then the fade will return to normal action. DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 16 8.4. "+" and "-" : Color Cycling Clock Adjustment The fluid changing of DAZZLE images is largely the result of a clock driven rotation of the display's color palette. The user can adjust the rate of this clock at any time by using the "-" (minus) key or the "+" (plus) key. Pressing "-" reduces the clock rate, pressing "+" increases the clock rate. Note that DAZZLE defaults to maximum speed in VGA modes, and almost maximum rate in EGA modes. When either the maximum or the minimum clock rate is reached the console emits a short tone. This process is distinct from, yet can complement, the palette control command line options (see descriptions for "/A" and "/M" options above). 8.5. "PgUp" and "PgDn" VGA Color Cycling Step Adjustment The degree of color change that occurs at each event of the color clock can be adjusted on VGA displays using the "Page Up" (PgUp) and "Page Down" (PgDn) keys. The program starts in the minimum step condition when loaded. This effect is distinct from, yet strongly complements, the "+" and "-" key functions described above. 8.6. Shf-F10 : Reinitialize the Color Palette Pressing the "SHIFT" key and also the "F10" function key simultaneously (Shf-F10) causes the current color palette of the display to be reinitialized to a new random condition. There is a short tone at the start of the request, and another tone when the process is completed. In EGA modes the process is almost instantaneous. In VGA modes it can take up to a few seconds, and the Cap Lock LED will light while the new palette is being computed. Refer to the Cap Lock LED description for further details. 8.7. CTL-F10 : Select New Background Color Pressing the "CONTROL" key and also the "F10" function key simultaneously (CTL-F10) causes the background color of the current display to be changed to a new random value. 8.8. The Fade Control keys DAZZLE allows the user to select which fades will be used. The actions of these keys vary slightly depending on the current mode. In "Auto" mode, pressing one of the fade keys sets which fade will be used next but allows the normal image generation process to continue. In the "Semi-Automatic" mode the fade keys induce the selected fade immediately. The "Fade Enable Control" screen in the "Configuration" menu shows which key (without the "Alt", "Ctl", or "Shf" keys being used) can be pressed to select a specific fade algorithm. 8.9. Special Fade Control keys The following behave a little differently, so they have been set aside for special discussion. DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 17 8.9.1. P : Pan/Scroll fade Unlike the previous fade keys, this one has to be pressed at a certain time to have any effect in the "Automatic" mode. When DAZZLE is drawing in "Auto" mode it is in the "Auto-DAZE" state (no LED's are lit, see details above about LED usage). Once the last image has been drawn it switches to the "Fade-Out" state (the Scroll Lock LED is lit). The first thing this latter state usually does is just pause for a while so that you can appreciate the incredible beauty of the display. The "P" key is only recognized in "Auto" mode if pressed while still in the "Auto-DAZE" state (before Scroll Lock lights). Once the last image has been drawn and the pause delay starts this key will simply be ignored. If a Pan/Scroll is in progress as indicated by the lighting of the Num Lock LED, then pressing the "P" key will assure that both a pan and also a scroll are presented. In the "Semi-Automatic" mode this key will not induce a Pan/Scroll. Since that effect is not supported in the "Semi-Auto" mode, pressing "P" causes one of the other fades to be randomly selected and executed immediately. 8.9.2. H : Hold current display This is distinct from, yet similar to, the "freeze" command that is called with the "TAB" key. This key is simply ignored in the "Semi-Auto" mode. In the "Auto" mode it lets the "Auto-DAZE" state (refer to Pan/Scroll description above) continue to normal completion, and will even let a Pan/Scroll proceed normally if one happens to have been selected by the "Fade-Out" state. But it causes the "Fade-Out" state to jam in the pause delay mode forever. Here the program will wait until you manually select a fade. Note that the fade that you select will commence immediately. The Scroll Lock LED will light solidly, indicating that user intervention is required to allow the program to proceed normally. Refer to the Scroll Lock LED description above for more details. If you press "H" as soon at DAZZLE enters the pause delay mode, then any fade select key, the delay is effectively canceled--allowing you to immediately induce any fade you wish. 8.9.3. N : Next display now This key has been made immediately effective in all modes. It stops any current image generation or fade, and begins a screen clear process. This is the fastest way to blank the screen. 8.10. Mouse Clicks DAZZLE will test for the presence of a Microsoft compatible Mouse driver. If any mouse button is pressed (or if the screen is contacted when using a Touch Screen system that is Microsoft Mouse compatible) DAZZLE will usually interpret that action as being the same as pressing the "ENTER" key. Note that in the text menu subsystem of this current version a mouse click aborts the program. DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 18 9. KEYS ACTIVE IN "SEMI-AUTO" MODE DAZZLE supports a whole set of commands to allow the user to control the image generation process of the program. Refer to "Selecting Modes" above for details on accessing the "Semi-Automatic" mode. Note that configuration options that disable a fade cause that fade to be unavailable in the "Semi-Auto" mode also. In addition to the keys described in the "KEYS ACTIVE IN ALL MODES" section above, the following keys can be used while in the "Semi-Auto" mode. 9.1. F8 : Toggle continuous drawing mode This key is similar to the F10 Draw Current Image key, except that "F8" will draw the selected image continuously until the next press of the "F8" key. All other keys maintain their normal function even while the continuous drawing mode is active. This mode is switched off when you exit 'Semi-Automatic' operation, but remains active through a fade or menu access. Review the section below with the F10 key description for more details. 9.2. F9 : Select Random Image If the user wishes to let DAZZLE randomly select the next image generating algorithm to be drawn then press the "F9" function key. It selects another image each time it is pressed. Note that specific images can be selected as detailed below. 9.3. F10 : Draw Current Image Once an image algorithm has been selected by whatever means, the "F10" key is pressed to draw that image. The image will be drawn for as long as you hold down this key. You may release the key, and when you press it again it will simply resume where it left off if you have not pressed another key. It is suggested that you start an image with just a tap of this key, note what it is doing, and then decide how long you wish to hold it. Since there are no limits on image generation time with this key, you can let a really interesting pattern grow continuously, producing visual effects that "Auto" mode will never duplicate. This key will remember the image being played even if you perform a "fade". So if a great image gets too busy, you can "fade" it and press "F10" again and pick up where you left off. Due to the behavior of the "typematic" key repeat built into the keyboard controller, it is possible for DAZZLE to get confused about when you release the "F10" key. If this happens then the selected image will continue drawing after you release this key. Just a quick tap of this key again will bring it to a halt. 9.4. Alt-F10 : Reinitialize Current Algorithm This key allows the continued use of the same currently selected image algorithm. But it causes the image algorithm to be reinitialized to new random settings. This is most useful for changing between various modes of the same algorithm. Some images support use of exclusive-OR for "ghosting" DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 19 or mosaic texturing, some can change shape, most will change color and screen location when this is pressed. 9.5. Specific Image Selection Keys It is possible to specify exactly which image algorithm you wish DAZZLE to use by pressing one of the Alt-keys 0 through 9, or A through Z. Press the "Alt" key, and a letter key or number key (use the numbers along the top of the keyboard, not the ones over on the side calculator pad). Each represents a specific image selection. The "Image Size" display in the "Configuration" menu list the name of each algorithm, and the Alt-key that can be used to select that image. In addition to the Alt-keys pattern selection, Ctl-keys A through Z can be used to select images that are detailed in the second "Image Size" display in the "Configuration" menu list of algorithms. 10. CONFIGURATION DAZZLE allows the user to customize many of the characteristics of the image generation and fade actions. At any time you may press the "F2" function key to activate the configuration menu subsystem. This system offers useful enhancements and controls. 10.1. Cursor Keys within CONFIGURE When within the configure subsystem DAZZLE recognizes the various standard cursor keys. The "HOME" key jumps to the first entry field of the current screen. The "END" key jumps to the last entry field of the current screen. The "PgDn" key advances to the next screen, the "PgUp" returns to the previous screen. The arrow keys also can be used. Note that the bottom right of the text window shows what page movement keys are valid at that point. 10.2. Exiting CONFIGURE The text menu subsystems, including the configure system, can be exited by pressing the same key that invokes that subsystem. Thus to exit configure press the "F2" key again. 10.3. Image Size Control These two screens allow the user to customize the images generated in the "Auto" mode of DAZZLE. When an image is called, it is allowed to draw on the display for a variable amount of time, the duration of which centers around the number entered in this menu. This number is multiplied by an internal value that reflects the size of the display and the resolution of the current active video mode. Therefore these numbers are relative and not absolute in their impact. Since the screen resolution varies from EGA to VGA, it is also true that the maximum value that can be entered changes between video modes. You may enter any large number, DAZZLE will reduce your input to the legal range for the current mode. The minimum value is 0, thus allowing the complete disabling of images as you desire. At least one DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 20 image must have a non-zero value, a configuration file that fails this criteria may cause DAZZLE to abort during startup. As the "Image Size" number is increased the selected image is allowed to draw longer, producing either larger patterns, more patterns, and/or a greater variety of pattern variations. The "KEY" field shows which Alt-key or Ctl-key (refer to "Specific Image Selection Keys" above) will select that specific image drawing algorithm. The "NAME" field shows the internal name of that image. The "SIZE" field shows the current relative size limit for that image. Note that the first Image Size screen is for use with Alt-key images, and the second Image Size screen is for use with Ctl-key images. 10.4. Fade Enable Control This screen allows the user to selectively enable or disable specific fades. If disabled, the fade will be unavailable in either "Auto" or "Semi- Automatic" modes. If the user presses a fade command key (refer to "The Fade Control Keys" above) for a fade that has been disabled then DAZZLE will randomly select an enabled fade to execute. Note that in addition to the listed fades, DAZZLE uses a "fade to black" process to clear the screen at the end of each fade. The "KEY" field shows which key (without the "Alt", "Ctl", or "Shf" keys being used) will select that specific fade algorithm. The "FADE" field shows the internal name of that fade. The "ENABLE" field shows the current state for that fade. 10.5. Auto Mode Display Customization This menu shows two numbers; "Minimum images per display" and "Maximum images per display". These values control the number of images that will be overlaid on a single screen during the Auto Mode of operation. When set to small numbers only a few images will be mixed together on one display prior to the next fade. This reduces how busy the screen becomes. When set to large numbers many images will be mixed together on a display prior to the next fade. This creates a much more complex display. This menu also allows you to control how long the program pauses in an idle state before initiating a fade. This time is provided to allow a screen to be appreciated before it is removed. The bottom of this menu states, "These numbers will be increased if in Alternate or Mad mode." What specifically happens is that if the program is operating in the Alternate (faster color cycling) mode then the number of overlaid images is increased by up to the number you entered as a minimum count (i.e., #images = (min+random(1+max-min)+random(min))). If the program is operating in the Mad (fastest color cycling) mode then the number of overlaid images is increased by up to the number you entered as a maximum count (i.e., #images = (min+random(1+max-min)+random(max))). DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 21 10.6. File Access Menu This screen allows the user to save or load a DAZZLE configuration file. There are three entry fields on this screen. Two additional function keys are also recognized only when viewing this screen. 10.6.1. Select Mode At this entry the user can select either to "Save" the current configuration information, or to "Load" an existing file. Press either the "S" key or the "L" key, then "ENTER". 10.6.2. File Name At this entry the user can specify the file to be saved or loaded. Note that a default name is provided if one was not used at program invocation. To replace the name simply begin typing it in, and press "ENTER" when completed. It is suggested that a file extension (the last three characters in the name, on the right of the period) of ".DZL" be used. The following extensions are illegal : .BAT, .COM, .EXE. Beneath this field is an unmarked "File Status" field. If you attempt to load a nonexistent file this will show "NOT FOUND". If you try to save over an existing file this will show "EXIST", unless the file is protected from overwriting, in which case it will show "READ ONLY". If you specify a wildcard character ("*" or "?") within this entry, then DAZZLE will automatically invoke a directory list to aid in your selection process. 10.6.3. Path The current disk and directory path is displayed in this field. You may specify any variation of disk and path information that DOS would normally support. Each of the following are legal: .. (changes to previous directory) C: (changes to C drive) \MT (to MT directory on current disk) D:\ (to root directory on D drive) 10.6.4. F3 : View Disk Directory Pressing the "F3" function key invokes the disk directory display. Note that if you have begun an entry in any of the menu's fields you must press "ENTER" before this key can take effect. Once a disk directory is displayed you may use the various cursor keys to move around. Arrow keys work, and the "HOME" key jumps to the top of the display, the "END" key jumps to the bottom. The "PgUp" and "PgDn" keys can be used to move about more quickly. Press "ENTER" to select a specific file, or "F3" again to exit this display. If you select a field that ends with a "\" (backslash) character, you are selecting a directory, and the display will be updated to reflect the contents of this new default path. The path field in the File Access Menu also will be updated to this new path. DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 22 File names displayed in lower case letters are "Read Only". 10.6.5. F4 : Execute Save/Load Once the desired file has been specified, the "F4" function key can be pressed to execute the specified command. If the "F4" key is ignored, then you may still have a pending input entry; simply press "ENTER" then try the "F4" key again. 11. USAGE WITHIN WINDOWS DAZZLE has been tested with both Windows2.0 and Windows3.x, both with excellent results. While a true Windows Application Interface is available from MicroTronics, this version is very usable as is. DAZZLE can be left inactive in the background, and brought up on the screen where it was last interrupted with a simple Alt-TAB (or equivalent) key press. In Extended 386/486 system the DAZZLE image will start intact from an interruption, otherwise the image may be corrupted when DAZZLE is first resumed but it will correct itself once the next fade operation is completed. As a basic starting point create DAZZLE.PIF with these entries: Program Parameters : /W Memory Required: 350KB, Memory Desired -1 Display Usage: Full Screen Close Window on Exit All other options should be disabled. Especially avoid any video monitor selections. If you are not using a 386/486 computer you may not be asked to set each of these options. 12. CONFIGURATION FILE FORMAT The file that is used by DAZZLE is an editable text file that follows a simple format. Each entry in the file must be on a separate line, and consist of a "Key ID" and a "Configuration Value". It is suggested that the user invoke DAZZLE in it's default mode, use the File Access Menu to "Save" a copy of the program's configuration. That file should then be printed. With DAZZLE in the Configuration Menu mode, a printout of the configuration file, and a copy of this document in hand, the whole process should prove to be very clear. 12.1. Shift Key Tokens A token in DAZZLE is a character that represents a condition. In order to represent within the configuration file the condition of the three shift keys-Alternate, Control, Shift-a group of tokens have been assigned as follows: Alternate = ~ (Tilde character) Control = ^ (Caret character) Shift = ` (grave or backwards-quote character) Thus to specify the Alt-A key, the file entry would be "~A". To specify the Ctl-F key, the file entry would be "^F". DAZ50-200592 Programs & documentation (c)c1992 MicroTronics 23 12.2. Special Token This file also contains a special token to allow the specification of menu configuration entries that do not match any shift key function. The "$" (dollar) token is used to mark such a field. The values for Auto Mode Display Customization are contained in this file as: $I : the mInimum number of images on one display $X : the maXimum number of images on one display $F : Fade delay time in Auto mode 12.3. Key ID A "Key ID" entry in the file consist of the key to be designated, with an optional shift key token prefix. Refer to Shift Key Tokens above for examples. 12.4. Configuration Value The value to be specified must be surrounded in square brackets; "[" and "]". If the value is for an Image Size or configuration entry, then the use of an unsigned integer value is required. Unsigned meaning no "+" or "-" values. Integer meaning no fractions, decimal points, or exponents. Therefore legal values are: "[25]" or "[0001]" or "[ 99 ]". Illegal values would include: "[-1]" or " 25]" or "[14.5]". If the value is for a fade entry, then the use of either a "Y" or an "N" character is required: "[Y]" or "[N]". 12.5. Comment Lines While reading (parsing) any line of text in the file, when a ";" (semicolon) is encountered DAZZLE stops reading that line. This allows the liberal insertion of various comments within the file. DAZZLE is very casual about parsing this file. It tolerates extra space and tab characters, so you can generally make the file look any way you like. 12.6. Version Flag The first non-comment line in the file should be the version flag. It consists of a "#" (hash) character followed by an unsigned integer of the DAZZLE version of the creating program. This is intended for future compatibility between upgrades and should not be changed. 13. PROGRAM INTEGRITY All reasonable effort has been made to assure that the use of this program on any compatible computer system can have no detrimental side effects. In addition to extensive Quality Assurance testing, the DAZZLE program contains an internal integrity check (read the section on the "/I" command line option above). If someone makes any code modifications to this program, it probably will be detected and the program will refuse to execute. Any persons making unauthorized modifications will be aggressively pursued and prosecuted. As of revision 5.0 the antiviral system uses a faster and better CRC checking algorithm. 14. PROGRAMMERS COMMENTS DAZZLE is written mostly in Borland C 3.0 (copyright Borland). Assembler code for direct video control was used mostly due to two characteristics of DAZZLE: all image generation is done a single pixel at a time, thus video write mode 2 was needed for EGA speed; secondly, the VGA mode uses the not-so-standard but highly portable 320x400 mode instead of the normal BIOS supported 320x200 mode. Talented and accomplished people are always an asset. If you might be interested in contributing to a MicroTronics project, then please write, and if possible include a sample of your work.
