Uh, just to clarify, you will NOT find any SET_GRAPHICS_FUNCTON
calls in any code I provide. :-)

I really don't care for that technique because I don't think
it looks "professional" on many computers. I always use
a DEVICE, COPY technique for drawing on graphics plots
that use direct graphics.

Just didn't want my reputation besmirched more than it has
been lately. :-)

Cheers,

David
