Wait a minute: I thought that El Cal (and therefore Sub Cal) is
purely a numerical tool.  The original poster asked for a symbolic
math package.  The only ones I know of are form, available for free on
atari.archive, and Maple.  Form is very general, but ha a steep learning
curve, and requires that you program (recursively) in its own language.
I saw a post a while ago that mentioned that Maple has been ported to
the ST (~$400?), but I don't know anything beyond that.
