Chris,

There are several ways to do this and the method of creating variables
as mentioned by Thomas is a good route to go. You can get quite fancy
with this by using a little MIF trick to include a baseline offset to
a character tag instead of using the superscript (as this is fixed
globally for each document and may not be optimal for any given
typeface when creating fractions). Use the <FDY> to vertically kern
and the <FDX> to horizontally kern by percentages of an em. You can
create special character tags in a small MIF file and import them into
your documents (since these properties, at least the vertical kerning,
aren't directly addressable in the Character Designer).

Another approach is to get a Fractions font such as Helvetica
Fractions or New Century Schoolbook Fractions and use those to set
them.

FM doesn't do unicode, so forget about accessing any special glyphs
outside of the first 256 positions of a standard font.
