Hi there I have some C programs written in an old Turbo C compiler (Version 2.01) that present basic 2-D graphics. I now want to run the same programs but present the graphics using high resolution beyond those available in the BGI of Turbo-C (e.g., 1600x1200). However, I am having trouble installing GRX246 in the Turbo-C compiler. How can I modify makedefs.bcc and/or makefile.bcc in such a way as to successfully install it? Also, using GRX within the Turbo-C environment will it be possible to run graphics at a 1600x1200 resoultion or am I better off switching to a more recent Borland compiler or a 32-bit DJGPP compiler? I have read on a forum like this that when running dos-based programmes in Windows XP, it is not possible to get better resolution than standard VGA - is this is the case? Thanks for your help Jared
