mathcal letters

[Angela Partain]

Thanks for your reply, Mimi and Robin.  I do believe it is a font problem.
I tried running the tex file you suggested, Mimi, and it just substituted
Courier for the mathcal letters.  I recently upgraded to Yandy 2.2.8 and I
do have mathtime.sty, so I'm not sure why I wouldn't have the font needed
for the \mathcal command.  Anyway, I'll keep workin' on it.
Thanks again,
Angela

In that case, it appears the same size as a normal letter, rather than
superscript size.   I tried this:
