Again: It's bad practice, you shouldn't do it. You may be able to save
100 screen captures this way on your machine (with 32MB RAM), but then
try to take it to a machine with 2MB RAM and no virtual memory, and
see what happens...

Or, what if you later use the same code for another purpose,
forgetting that it causes a memory leak, which saves the screen many
thousands of times?

If you really want to save on typing, why not just write a fucntion,
something like this:

--- begin ---
void SaveScreen(char *fname)
{
  BITMAP *bmp;
  PALETTE pal;

  get_palette(pal);
  bmp = create_sub_bitmap(screen, 0, 0, SCREEN_W, SCREEN_H);
  save_bitmap("dump.pcx", bmp, pal);
  destroy_bitmap(bmp);
}
--- end ---

Save it in a file, put it in a library, write a header, and voila...

Davin.
