Could some please tell me why this program doesn't get past
the compiler? It tells me that "es is an unknown register."

As you can probably tell from the mid-bending simplicity of
the code below, this is my start with djgpp, but I have run
the compiler on several other programs without any problems.

Also, is an inline rep stos used this way the optimum way
of drawing horizontals in djgpp? Watcom has a really smart
memmset with a Duffy switch. I looked through the library
help looking for something similar, but I'm still rather
confused over which library fns can get at vram safely.

Thanks,

Jonathan
