I think calc is great!

I also just found cc4 (Calculus Calculator) for MS-DOS that seems to
have many of the capabilities of Calc plus builtin graphing (screen
and printing).  Shareware I think.  The author mentions that
prentice-hall sold version 3 with a 200 pg manual for $30 or $40, but
he doesn't ask anything for this version....
