Along similar lines, I recently rewrote the dos.c module of STEVIE to use the Turbo-C text library for FAST output, and discovered that the library routines are HARDCODED for a 25-line screen!! This includes the gotoxy(), insline(), delline() etc.. The hardcoding is in an internal routine which initializes the default text window data structure used by these routines. If it is patched (in two places), then all of the other routines look like they ought to work just fine. The trick is.. HOW does one patch a routine in the Turbo-C 2.0 libraries? Without source code? Hmmm.. just need a good binary editor, I guess. Perhaps I'll give Borland Tech Support a call and ask about this.. Meanwhile, I further altered STEVIE to correctly determine the number of lines available, and it uses the TURBOC stuff if the screen has 25 lines, and it uses the ANSI escapes for any other size (30, 40, 50, 60 lines..). Works fine. -- ______Mark S.

I know there is another set of library functions which do not have this limitation: I used to have them. I got them off the Borland Forum on Compu$serve. -- Doug.
