We ask that you use WASP.for a few weeks to determine its value. If you)believe it is worth the asking price, you-register your copy and we send you the latest*version registered in your company's name..These Help windows give a general introduction-to WASP, and describe its capabilities. There,is also information on what to do when faced,with the opening screen. Please press <PgDn>-and <PgUp> to scan through this introduction.-WASP is a replacement for traditional printed,Steam Tables, but it goes further in that it+provides a much wider set of properties, it-eliminates the need for interpolating between+data points, and it will work in any of the.generally accepted units, even allowing mixingof systems of units.-It contains data for 15 point properties, and%17 temperature and pressure dependent+properties.  Most of the correlations cover*the range from -100 °C to 800 °C and up to*1000 bar, and some extend even beyond this.range.  Calculated data points match publisheddata very closely./WASP can be used in two different ways, so that)its use is similar to using printed Steam(Tables, but of course easier and faster.-The first way is when you know the conditions/of the ice, water or steam and you want to find,the physical properties.  If you are working+with wet steam you can also enter the steam/quality to get some of the combined properties..The second option allows you to search for the-conditions that give rise to a specific value-of the enthalpy, entropy or density.  This is(useful when doing calculations involvingcompression or throttling.-The programme has been carefully designed for)speed and ease of use.  On-screen prompts.appear at every step to guide you. In addition(there is context sensitive, on-line Help.available at all times. If you are ever unsure/of what the programme expects you to do, simply-pressing the <F1> key will open a window with.detailed instructions and information. You can(also view any Help Screen at any time byselecting it from a Help Index..A detailed manual is provided on the disk as a.text file.  You can print the manual by typing*PRINT WASPBOOK.DOC at the DOS prompt or by,pressing <Alt P> at the WASP opening screen..The opening screen shows the version and copy--right information.  It also shows to whom the,copy of WASP is registered.  This screen can)be bypassed by pressing (almost) any key.,At the opening screen you can press the <F1>.key to get Help, which is probably how you got/here.  If you press <F1> again you will see the.index of all the other Help Screens available..If you have a colour card in your computer you*can use <Alt C> and <Alt M> at the opening.screen to switch between mono and colour. This.is useful on portables which have colour cardsbut monochrome screens.-All the menus in WASP follow exactly the same0format. There are three ways to make a selectionfrom a menu.2The first is the "Point-and-Shoot" method. Use the-arrow keys to highlight your choice, and then2press <Enter>.  The second method is basically the0same as the first, except that the mouse is used/to highlight the choice.  The left mouse button0functions as an <Enter> key and the right buttonas an <Esc> key.1The third method is the fastest, requiring only a0single key press.  Simply press the alphanumeric!key corresponding to your choice.0At any stage during the running of the programme/you can press <F1> and get help on the specificitem on which you are working./Once you are in the Help window you will see in the top right corner the message/                                    Page x of y0If there is more than one page of help available1you can page through the help windows by pressing,PgUp, PgDn, Home and End. The message in the2bottom right corner tells you whether you can page1up or down. There will also be flashing arrows on.the right hand side that show if there is more%data above or below the current page.2If you press <F1> again you will be shown an index-of all the help available for this programme.2From this index you can select any one of the help1topics that are available. Simply use the <Arrow>/and <Page> keys to highlight the topic on which"you want help, and press <Return>.2After you have read that help topic you can return1to the Help Index by pressing <F1> again. You can/switch back and forth like this as often as youlike.0When you have read all the help you want you can2return to where you left the programme by pressing<Esc>.+This set of help windows describes the WASP1licensing policy.  If you want to know more about1Shareware in general please press <F1> and select'"Shareware Distribution" from the menu.1The WASP licence agreement is basically the usual.Shareware policy.  Recipients of copies of the2WASP package are requested to use the system for a0few weeks to determine its value.  You only need/to pay for it if you believe that it offers the/value of the asking price.  If it does not meet2your needs or standards then it costs you nothing.1WASP can be bought either as a single-user system1for US$ 40.00 or as a multi-user site licence for-US$ 75.00 ( or the equivalents in SA Rands )./The single-user licence entitles you to install1the package onto several different computers on a0single site, provided that it is not run on more1than one machine at a time.  If it is likely that,it will be run simultaneously on two or more,machines we request that you purchase a sitelicence.0You can pay for your WASP registration by credit0card, or by having the cost added to your Compu-.Serve account, or by sending a cheque or moneyorder to us..Full details on the registration procedure are.available by pressing <Alt R> at the Shareware'Distribution screen, and in the manual.0In return for your registration fee we will send2you a copy of the latest version of WASP with your2company's name listed as the licence holder on the
title screen..We do not send printed copies of the manual to1purchasers of WASP.  Instead there will be a file2containing the manual on the disk for you to print1out.  This is done for three reasons.  Firstly it2keeps the price down, secondly it allows revisions2and improvements to be included immediately rather2than having to run down stocks of old manuals, and-thirdly we believe that well-written software2should not need a manual !   What is your attitude/to manuals ?  Do you read them ?  Please let us-know if you feel a printed copy is important.1What else do you get for being honest and sending2in your registration fee ?  Well, we can't promise0to fill your post box with junk mail, but if you/don't register we have no way of telling you of+updates and of our other software products./Registered users are also entitled to 12 months1support by mail.  If you have any problems please0write and we will do our best to help.  We would0also like to hear of any features you would like/to see added to WASP.  Are there units that you2use that we have not built in ? Let us know and if&they are anything more reasonable than.bathtubs/fortnight we will build them in.  Are/there standard calculations that you would like2built in ?  If so please send details and samples.0Whether you register or not, may we request that-you give away copies of WASP to your friends,.colleagues, customers, suppliers, students and2anyone else who would have a use for it.  We would2also appreciate it if copies are uploaded to BBSs./The only restriction on distribution is that we0ask that you always give away copies of the full0system with all its files, and that they are notmodified in any way.2Suppliers of hardware and software may bundle WASP0with any of their other products, subject to the0above restriction, and that it is clearly stated-that any payment made is solely for the otherproduct and not for WASP.)      REGISTRATION TO ENGINEERING SCHOOLS)      ===================================/Any University or Technical College involved in0the tertiary education of engineers can obtain a1licence for WASP free of charge.  In order to get1your registered copy of the latest version please0send your registration form to our South African1address -  *NOT* to PsL or CompuServe.  Enclose a)covering letter on your School's officialletterhead, but send NO MONEY..All that we ask in return is that you make the-registered copy available to all students and/staff so that we do not get duplicate requests,1and hopefully the students will take their copies)with them when they go out into industry.+This program is produced by a member of the1Association of Shareware Professionals (ASP). ASP/wants to make sure that the shareware principle-works for you. If you are unable to resolve a/shareware-related problem with an ASP member by2contacting the member directly, ASP may be able to.help. The ASP Ombudsman can help you resolve a/dispute or problem with an ASP member, but does*not provide technical support for members'	products./Please write to the ASP Ombudsman at 545 Grover"Road, Muskegon, MI 49442-9427 USA,1FAX 616-788-2765 or send a CompuServe message via,CompuServe Mail to ASP Ombudsman 70007,3536.2The Shareware distribution system can be seen as a0natural development from the environment of free0enterprise and innovation that characterised the2PC industry in the early 1980's.  It has continued1to grow and today there is a huge variety of high0quality software available at reasonable prices.2Shareware in fact covers a wider range of subjects1than commercial software.  Some of the areas that0are particularly well represented are databases,.word processors, spreadsheets, CAD, games, DOS1utilities, menuing systems, education, accountingand programming support.0A support industry that includes magazines, disk1distributors and bulletin board systems has grownup around the Shareware system.2If you are new to Shareware you may like to have a/look at some of the software available from the1disk distributors.  They supply evaluation copies2of Shareware packages for about US$10.00 per disk.0This payment is for copying the software and the-price of the disk, and  NOT  for the software/itself. If you like the software, you send your1payment to the author and not to the distributor.-Some distributors with good catalogues are :-21  Public Brand Software, Box 51315, Indianapolis,&   IN 46241, United States of America.+2  The Public Domain and Shareware Library,+   Winscombe House, Beacon Rd, Crowborough,   Sussex, TN6 1UL, England.23  JSE, 73 Highway, Fish Hoek, 7975, South Africa.1The basic concept of Shareware is that the author.retains the copyright and all other commercial/rights to the software and documentation, while2allowing, and indeed encouraging, wide copying anddistribution of the package.2There are a few restrictions that authors place on0distribution.  All copies must be full copies of+the entire package with no modifications or0additions.  Copies may not be sold for more than1the cost of the disk, the labour of copying and a+reasonable profit.  When selling copies the0distributor must state that the software is free0for evaluation purposes only and payment must be.made to the author if continued use is made ofthe programme.2Effectively the Shareware author is relying on the/users of his software to do his marketing.  For/this reason Shareware is often also called User2Supported software.  This system eliminates almost1all the advertising and marketing costs that make0up the major portion of the operating budgets of!commercial software distributors./There are many advantages in Shareware to users1and authors.  The cost to the user is low because+no money is wasted on advertising and fancy1packaging that add no real value to the software.1The biggest advantage to the user is that it is a/true "try-before-you-buy" system.  The software1can be fully evaluated on the user's hardware and.in his own environment before payment is made.1Another advantage to the user is that by its very0nature Shareware cannot be copy protected.  This,eliminates the hassle of key disks, dongles,0immovable sectors on hard disks, special install2and uninstall routines and all the other wonderful0schemes that have been devised to try the user's	patience.2As there is no middleman (middlemen ?) not only is0the cost kept lower, but the user is also closer2to the author and is able to write directly to him1for help and advice.  Shareware authors generally2encourage users to send in "wish-lists" of desired+features, and are quite responsive to those	requests.2There are of course also advantages to the authors/who use Shareware to distribute their products.1The cost of launching a new product via Shareware1is much less than via normal commercial channels.2This has allowed smaller software houses to market/innovative and highly specialised software that1would otherwise simply not be profitable. Running1costs are also lower as marketing and advertisingcosts are much reduced.2The software industry is currently going through a1consolidation phase with the big-boys buying each0other, and some of the smaller boys, out.  But a.significant number of the small companies have/switched to Shareware and have made some really,top class software available via this route./The Data Entry screen allows you to specify the.temperature and pressure at which the physical-properties will be calculated.  ( To find the1conditions for a known value of enthalpy, entropy1or density use the Search function, ie <Alt S>. )0Apart from specifying these conditions there are1other options available on the Data Entry screen.2Pressing <F3> will display the physical properties.that do not vary with temperature or pressure.0Pressing <F4> allows you to specify the units in*which your entry is made, and in which the,properties will be displayed.  If you have a1colour video card <Alt C> and <Alt M> will switch.between colour and monochrome.  If you want toexit WASP press <Alt X>.0If you want to calculate the physical properties-under SATURATED solid/vapour or liquid/vapour)conditions you need to specify either the1temperature or pressure, but not both.  The entry1must be made on the top line and the <TAB> key is-used to select which of these you will enter.0E.g. if the programme is requesting you to enter1the temperature on the top line of the input box,1but you want to specify the pressure, press <TAB>to swop the two lines.1Under saturated conditions it is not necessary to/press <ENTER> after you have keyed in the first+number.  Just press the <SPACE BAR> and the/corresponding saturation value will be inserted&and the properties will be calculated./If you are working with wet saturated steam the-quality of the steam must be entered from the/Results Screen and not at the Data Entry stage.+This allows you to change the steam quality.without having to go through the complete dataentry procedure each time.0In order to calculate the physical properties at+conditions other than saturated you have to/specify both the temperature and pressure.  You0can swop the two entry lines with <TAB>, and you.can move the cursor from one line to the other/with the up and down arrow keys.  When you have.keyed in the value on the bottom line pressing/<ENTER> will calculate the physical properties.0During data entry the left and right arrow keys,0and the <HOME> and <END> keys, allow you to move1the cursor back and forth within the entry field.0The <DELETE> key deletes the character under the*cursor and the <BACKSPACE> key deletes the+character to the left of the cursor.  <Ctrl.BACKSPACE> will delete the entire entry field.0If the entry field already contains a number and1you press a numeric key before any of the editing0keys, the programme will assume that you want to/over ride the original entry and will delete it2before displaying the character you have keyed. If1you want to accept what is already displayed justpress <ENTER>.2If the first key pressed is the delete or a cursor/key, the programme will assume that you want to1edit the pre-existing entry.  Use the cursor keys1to position the cursor where you want to make the2change, and then type the new numbers.  Data entry2always works in INSERT mode, i.e. characters under/and to the right of the cursor will be moved to.make space for the new character.  In order to0type over characters they must be deleted first.0Only numeric characters will be accepted, except+that <e> can be used to signify exponential0notation.  E.g. the value 2000 can be entered as)2e3,    and 0.001 can be entered as 1e-3.2There are several different formats for the result2screens that display the physical properties.  The/format of these screens varies according to the-phases that are present, and according to the1choices that you have made.  However, all screensfollow the same basic pattern.2The highlighted box at the top of the screen shows/the temperature and pressure that you specified/and also shows the phases that will be present./The main result box in the centre of the screen0gives all the physical properties, the units and0the values for each phase.  Every alternate line/in this box is highlighted to make it easier to"follow the line across the screen./The bottom line of the result box shows some of1the options available.  If you press <Esc>, or in2fact any alphanumeric key, you will be returned tothe Data Entry screen.2The <F2> function key toggles between the full and0brief versions of the output screens.  The brief1results screen gives the properties usually found2in "Steam Tables".  The full screen gives the same+information plus the less frequently needed.properties.  The brief screen is easier to use%because it contains less information.2When you exit from WASP, the programme will make a/note of which result screen you had chosen, and+will use this choice when it is re-started./Although it is not shown in the list of options0you can use the <F3> function key to display thefixed physical properties..The <F4> key allows you to choose the units in,which the properties are displayed.  You can2select standard sets of units, or choose the units.for each property individually.  Help on these0choices is available from the Units Menu screen.0If you have a colour video card pressing <Alt C>0and <Alt M> will switch between colour and mono-chrome output.1When working with saturated liquid and vapour the-steam quality can be set by pressing <Alt W>.2The enthalpy, entropy and density of wet steam can/be shown, if required and applicable.  It is of1course only available when working with saturated+liquid and vapour.  It is only shown on the."BRIEF" result screen.  You can switch to this2screen by pressing <F2> while the "FULL" screen isbeing displayed.0In order to set the steam quality, press <Alt W>0at the result screen.  This option is only shown)on the "BRIEF" result screen menu, but is0available from the "FULL" result screen as well./When <Alt W> is pressed from the "FULL" screen,0the output will automatically switch to "BRIEF".2The display of wet steam properties can be toggled0on and off.  The toggle is turned on by pressing2<Alt W> at the result screen and then entering the,steam quality.  It is turned off by pressing/<Alt W> again, and then pressing <F10> when thesteam quality is displayed..The setting of this toggle, and the last steam1quality entered, are retained when you leave WASP.ready for use as defaults in the next session.2Note that the steam quality is defined here as the0percentage of vapour present, whereas some textsrefer to the moisture content.1The physical properties of water that do not vary0with temperature or pressure can be displayed by0pressing <F3> at the Data Entry Screen or at the1Result Screen displaying the variable properties./The main result box in the centre of the screen1gives all the physical properties, the units used1and the values for each physical property.  Every1alternate line in this box is highlighted to make/it easier to follow the line across the screen./The bottom line of the result box shows some of2the options available.  If you press <Esc> or <F3>1you will be returned to the screen from where yourequested the fixed properties..The <F4> key allows you to choose the units in,which the properties are displayed.  You can2select standard sets of units, or choose the units0for each property individually.  Further Help on0making these choices is available from the Units1Menu screen, or by pressing <F1> now and choosing$Selecting Units from the Help Index.0If you have a colour video card pressing <Alt C>0and <Alt M> will switch between colour and mono-chrome output.+You can exit from WASP by pressing <Alt X>..The units that are used for data entry and for0displaying the physical properties can be chosen0in sets, or individually for each property.  The.first 5 options on the menu select the sets of0units and the balance of the options are for theindividual units./There are two ways to make a selection from the1menu.  The first is the "Point-and-Shoot" method.0Use the arrow keys to highlight your choice, and1then press <Enter>.  The second method is faster,0requiring only a single key press.  Simply press0the alphabetic key corresponding to your choice.1You can see which units are currently selected by1pressing <Space Bar> while the menu is displayed.+If you select one of the sets of units, the2programme will display the units that will be used2for each property.  Press <Esc> to get back to the-menu, and again to get back to the point from where you called the Units menu.*When you choose to change the units for an0individual property you will be shown a sub-menu.with the available units.  In the sub-menu the1currently selected unit will be highlighted.  The1method for selecting the option from the sub-menu0is exactly the same as for the main menu.  After*you make your selection the programme will1automatically return to the main menu, from where.you can choose to change the units for another2property, or you can press <Esc> to quit the menu.+The only individual unit that needs further0explanation is option "H", ie Density / Specific/Volume.  Strictly speaking density and specific2volume are not the same property, but in WASP they.are dealt with together as the one is just thereciprocal of the other./Whenever you exit from WASP, the programme will0check to see if the selected units have changed.,If they have, it will give you the option of0saving the new selection of units for use in the/next session.  You can revert to the last saved0selection of units at any stage during a session0by selecting the first option on the units menu..The Search function is aimed at easily finding/the conditions of temperature and pressure that1give rise to known values of enthalpy, entropy or.density.  This function can be called from the0Data Entry Screen or from the Results Screens bypressing <Alt S>.1After pressing <Alt S> you will be asked to enter2the Search Parameters.  On the first line you must0enter the value for any one of enthalpy, entropy/or density.  Before you enter the value you can-select the property you want to search for by+pressing <TAB>.  Once you have selected the/property, WASP will keep prompting for that one/each time you use the Search function until you"change it by pressing <TAB> again..If you have already used WASP to calculate the0physical properties at some conditions, you will2see that the entry on the first line has defaulted1to the calculated value shown on the last Results.Screen.  You can accept this value by pressing1<ENTER>, or you can simply type in the new value.0Entering a value in this field works in the same way as on the Data Entry Screen.2Under saturated conditions the Results Screen will0show values for each phase.  The Search function0follows a simple rule to select which value will.become the default - It always defaults to the.vapour value UNLESS it is displaying wet steam.properties and then it will take the wet steamvalue.0If you want to force the Search function to take2the saturated vapour value as the default you must+either disable the display of the wet steam-properties or enter a steam quality of 100 %.1Setting the steam quality to 0 % will effectively,make the saturated liquid value the default.,On the second line you must enter either the.temperature or the pressure, and the programme1will search for the other.  Here again you select1the property you want to enter by pressing <TAB>.,The default values will be the last ones you!entered on the Data Entry Screen.-While making these entries you can change theunits used by pressing <F4>.0After you have entered the Search Parameters the1programme will try to find either the temperature2or pressure that will satisfy them.  If the search/is successful it will then display the value it2finds, together with the fluid condition.  At this*stage you can press <ENTER> to see all the0properties shown on the Results Screen, or press(<Esc> to re-enter the Search Parameters..If no value can be found to satisfy the Search/Parameters WASP will advise you of the fact and/then you can press <Esc> to re-enter the Search0Parameters, or press <F10> to abandon the Search/function.  The programme limitations that could1cause the search to be unsuccessful are describedbelow./The range over which WASP can search for values1of the chosen properties is basically the same as2that where it can calculate those properties, withtwo exceptions.1The first is that it will not search in the solid2phase.  The second area that may cause problems is-searching for the pressure that gives a known2enthalpy in the liquid phase. At some temperatures1the enthalpy of the liquid first decreases as the0pressure increases, and then increases at higher/pressures.  The linear search technique used by0WASP fails under these conditions.  In real life this will rarely cause problems.0                          A word of caution ....-A word of caution is necessary when using the,Search function.  In some areas the physical0properties change very slowly, particularly with+changes in pressure.  A good example is the2entropy of liquid water.  If you take a value from2a set of Steam Tables, and then use WASP to search/for it, you may find that it reports a pressure2significantly different from the Steam Tables.  So0although WASP will very accurately calculate the1properties when given the conditions, the reverse2is not always true. This will be less of a problem0when working with changes in a property and WASP.is used to calculate the properties before and,after the change.  As always, for a critical,design, cross check with other data sources.2The instruction manual for WASP is supplied in the-form of a text file named WASPBOOK.DOC on the0distribution disk.  This means that you can make/your own hard copy of the manual by printing it.out on your computer's printer.  There are two-ways to make a copy.  The easiest is to press2<Alt P> at the WASP opening screen.  The other way0is to type PRINT WASPBOOK.DOC at the DOS prompt.-The manual is formatted to fit on pages of at/least 11 x 8.3 inches (279 x 211 mm) when using1a font with 10 characters per inch and spacing of16 lines per inch.  Most printers default to these/values when switched on.  A smaller font can be1used but will not fill the pages.  A proportional font will not give good results.2If registered users have problems that they cannot0solve by reading the on-line help or the manual,2they are entitled to support via mail for a period+of 12 months from the date of registration.1When describing the problem please be as detailed0as possible.  Screen dumps may be useful in this0regard (press <PRINT SCREEN> while the screen in0question is being displayed).  If you have oper-2ational problems include details of your hardware,0operating system, resident programmes and so on.,Write to us at  Katmar Software, PO Box 654,/Westville 3630, South Africa,  or send an emailmessage to CIS 100100,2050.1If you write, but also have a CompuServe address,2please include it and we will reply by email if itis feasible.0It is ASP policy that if an unresolvable problem2occurs within 3 months of purchase the customer is.entitled to a refund of the registration cost. !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~ÇüéâäàåçêëèïîìÄÅÉæÆôöòû
