	As for my earlier message as why my TextBlt did not work, I may
have a clue.  It turns out that the problem (I think) was in the size of the
raster form width.  I was using a form with a width of 4096 bytes, so maybe
a signed word value may have had problems.  I tried using a form with a much
smaller width (the system font), and it worked fine.  So, then I tried
a form width of 2048.  Nope, still didn't work.  Hmmm...  

	So, right now, I take the character I want, blit it from the big
form into a temporary form, and then TextBlt it.  This works!  It is 
interesting to note that normal GEM raster ops work fine with raster form
widths of 4096 bytes.  I wish I had some documentation that explained this
for sure...

	Also, I would like to thank Jwahar Bammi for his replies to my
TextBlt questions.  All of my letters got bounced back from case, so I
couldn't thank him personally.

	So, if anyone has any definitive ideas about this TextBlt/form width
thing, I would love to hear about it.
