HISTORY FILE FOR WCL -------------------- Version 6.10 (November 1993) ---------------------------- Fixed a bug in the search engine used for the SEEK, DIR /S and the DELTREE commands. Version 6.00 (October 1993) --------------------------- This is a major update. 1. New command "COLOR" introduced as an easy means of setting the foreground and background colors, and the wallpaper, respectively. The command inserts the supplied parameters into WCL.INI. e.g., "COLOR blue gray gray" 2. New command "GETCOLOR" introduced. This allows the user to see the current color settings in WCL.INI, without using an editor to view the INI file. 3. New command "CLS" introduced. This clears the screen, and the contents of any scroll back buffer. 4. A host of minor bugs have been fixed. 5. Due to popular demand, a new command "DELTREE" has been implemented. This command attempts to delete ALL the files in a given diretory tree. This includes all the files in that directory, and in its subdirectories. It then attempts to erase all the subdirectories in that directory tree. NOTE: I have implemented this command against my better judgment, because users demanded it. In my opinion, it is best left well alone. If anybody proceeds to use it, I am not responsible for any loss of data that may ensue. Because of the drastic nature of what DELTREE does, I have imposed some limitations; 1. You will be asked to confirm TWICE that you wish to proceed. 2. You must supply the name of a valid directory to the command. Just typing "DELTREE" will be rejected. You need to type something like "DELTREE D:\JUNKMAIL" 3. The command will reject any attempt to apply it to the ROOT directory of any drive. e.g., "DELTREE \" or "DELTREE C:\" these will NOT be accepted. 4. If there is any problem with deleting any file at all, then the process will abort. Version 5.10 (October 1993) --------------------------- 1. A new switch "/S" is added to the "DIR" command. This lists files in the directory tree, which match the supplied filespecs. Note that the files listed by this switch are NOT sorted at all. Note also that this switch CANNOT be used with any other switch that begins with a "/". Version 5.07 (October 1993) --------------------------- 1. Users can now set both the text and background colors. This involves three new settings in WCL.INI; [a] TEXT-COLOR= [b] TEXT-BACKGROUND= [c] WALLPAPER= See WCL.TXT or the help file for full details. Version 5.06 (October 1993) --------------------------- 1. Bug that caused text not to appear in the BIGWCL window on some systems was fixed. 2. Other minor bugs fixed. 3. You can now insert a space after your prompt by adding a hash ("#") to the end of the prompt (e.g., "PROMPT Hello:#" - this will cause a space to be inserted after the "Hello:". Do not use the hash with "$P$G". 4. Cosmetic changes made to the "DEL" command. 5. New installation program. This is now optional. 6. Default setting of the BIGWCL main window now set to provide a scroll back buffer. Version 5.05 (October 1993) --------------------------- The "SEEK" command has been rewritten. It now works by locating all the files that match the filespecs, searching through the whole drive. It can now accept wildcard characters. Version 5.00 (October 1993) --------------------------- 1. A new executable (BIGWCL.EXE) is added to the package. This is basically the same program as WCL.EXE, but with some differences; [a] the main window is big [b] the output from commands (such as DIR, COPY, TYPE) is in the main window, instead of in popup windows (as WCL.EXE does) [c] the executable does not require the library file WCLDLL.EXE [d] the introduction of BIGWCL.EXE has resulted in some more entries being added to the WCL.INI file, to cater for the screen co-ordinates of the BIGWCL main window. Apart from these new entries, BIGWCL.EXE uses the entries in the WCL.INI file in the same way as WCL.EXE [e] BIGWCL.EXE is probably faster than WCL.EXE for most commands, but uses more memory. I expect users to use either WCL.EXE or BIGWCL.EXE as their WCL program, since they do more or less the same thing. However, there is no reason why the user cannot use both of them. 2. New switches (/O[E,S,D] /L /W) are added to the DIR command, to increase compatibility with the DOS DIR command. The /W switch is only implemented in BIGWCL.EXE. The /O parameter is for changing the order in which the files are sorted. Type "DIR /?" to see the options available. Version 4.61 (October 1993) --------------------------- Fixed a bug involving copying files with the read-only attribute, from a write-protected disk. Version 4.60 (October 1993) --------------------------- 1. Parameters can now be passed to programs called in WCL batch files, just like in DOS. Up to 3 parameters can be passed to a program, through the use of "%" (e.g., %1 %2 %3). 2. Some minor bugs were fixed 3. Program efficiency has been improved. First, memory usage has decreased by about 40kb. This has been achieved by certain optimizations, and static linking of routines that were formerly called from a supplied DLL. Secondly, many operations are now marginally faster. Version 4.50 (June 1993) ------------------------ This is the first general release. The program has before now been released only to a few people, mainly friends and acquaintances. (c) 1993, Dr. A. Olowofoyeku 268 Horwood, Newcastle, Staffs ST5 5BQ ENGLAND.
