I too have written programs that find the DEFINITE integral and/or NUMERIC
derivative of a function at a certain point.  But, from what I have seen
of Derive/Mathematica type programs (which the original post refered to),
they are able to find the INDEFINITE integral and/or the indefinite (is
that the right term?) derivitive, that is, the function that expresses the
int. or der., not just the answer... But if all you want is the numeric
answers, or a function grapher, yes, Atari BASIC will do the job with not
very much problem at all!
