- Sun 8-Sep-91: I have been looking into entering keyboard input in
- Turbo Pascal graphics mode in the same way as one uses Readln in the
- text mode. This is something I have done some time ago with the
- ReadKey function in my graphics programs. I wanted, however, to make
- an enhanced version with line editing possible. In other words I
- wanted an input procedure that allows the usage of the BackSpace,
- Delete, CursorRight, CursorLeft, Home, End, and Escape keys.
- Furthermore, I wanted to make input recall (CursorUp) possible. The
- program that needed this feature is my updated graphics drawing
- program DRAWLINE.EXE in /pc/ts/tsdraw14.arc, but I first decided to
- try out these features in a demonstration program TURBDEMO.EXE. I
- have consequently updated my my package of demonstration programs to
- be /pc/ts/tsdemo15.arc.
-
- Fri 7-Sep-90: I have updated my package of demonstration programs to
- be /pc/ts/tsdemo14.arc. These programs are in fact by-products of
- writing my utilities and building up my Turbo Pascal routines
- library. Bigchar.exe and bigtime.exe result from looking at the way
- which text fonts are stored in the PC textmode. Plotdemo.exe and
- turbdemo.exe both result from needing and writing Turbo Pascal
- graphics routines. The former draws a number of different functions
- in CGA graphics. The latter is new to the package and it involves
- solving a number of problems that arise in Turbo Pascal graphics
- programming. These problems include some which have recently been
- discussed in the InterNet comp.lang.pascal newsgroup, such as having
- a different background color for each graphics window (when the
- screen is divided into several windows), underlining text, mixed
- colors to seemingly increase the number of available colors, etc.
