dos on win 95 why does my screen flicker when I run graphics prog and is it possible to run then in a window also can I do some input output routines then graphics then input output
without clearing the screen.

thx for the help all.

p.s. please can you explain what a double buffer is and show me an example.

you can set up a buffer in your memory to do all drawing operations to a frame, and then blast that entire frame to the video buffer at once, this way you get all changes at once, instead of seeing progressive changes on the screen... which is the flicker you are experiencing...
