Even if it is true that you don't have enough memory, a program
shouldn't crash.  Your code should test the values returned by malloc
and print an error message if it returns a NULL pointer.

If you run on Windows 9X, you can't.  64MB is the maximum amount
Windows will let a DJGPP program use.

CWSDPMI can only be used on plain DOS, ouside Windows.  If you can do
that, then it will let you use as much as 512MB of memory, if you have
enough RAM and sisk space.
