The range of superscripting/subscripting etc. is somewhat more restricted
than for vector fonts, if I remember rightly the list of ! commands is
given in the PS device section of the reference manual.
Special characters: some (including I think Angstrom) are in the 8-bit
charset, but you'll need to check out the mappings there is a routine in
the userlib that plots all the characters out (I suggest using a
previewer to look at the results as it makes about a hundred pages of
output). Others are in the symbol font (notably the greek letters) so a
gamma would be '!9g!3'. Note that neither the font number nor the letter
mapping is the same as for the vector fonts.

Hi,
Well, not sure about the * symbol instead of the X. But to to print
special characters, look at an ascii table, find the ascii code for the
symbol you want, and then use the string() command to convert it to a
character.
for instance, say we were kinda out of it, and couldn't type "A", we
could make an "A" with the following command
string(65b)
(the b is because 65 is a byte value)
to use it in part of another string, do something like the
following,
big_string = string(65b) + " dog jumped over teh fence"
As for super scripting and subscripting, don't think it is automatically
possible. These fonts you would use are X fonts, basicly fixed size
postscript fonts, and so are not scalable. (they are not postscript
fonts!!!) I guess you could do it with different size fint and use
xyouts to position slightly up or down and pick slightly smaller font
sizes.
-good luck,
-stephen
