As far as I know, there is no way to tell the Turbo Pascal Graphics
system to write to a specified memory designation instead of the display
screen in CGA mode.

At one time I wanted to do this also, but as I found out, what you need to
do is basically write your own graphics system and have it write to the
memory.  Its what I ended up doing.  CGA sucks.

Anyway, I suppose you could theoretically go in and debug your compiled
program and manually change the far address of the graphics write but
then you run into the problem of having to use and static memory area
that might trash other areas.  I can't think of any way to use a dynamically
allocated area of memory for graphics writes in CGA.  Sorry.

If anyone else knows a possibility, please jump in.  I'd like a simple way
to do it too.
