Thanks for pointing me in the right direction. What I need to do is SET_PLOT, 'Z'
[which is some sort of memory "pseudo device"], then do my plotting, then call TVRD
to capture it, then call WRITE_GIF to write it to a GIF file. If I'd scanned the
manual another 5 minutes, I might have come up with it on my own.
