We would like to have a calculator like function in an application we
are writing in Turbo Pascal. We have some home grown functions which
will be available from within the calculator. The functions are
basically complete but the user interface needs work. We would like it
to be free format entry of expresions. Is there any
commercial and/or public domain software available for creating such a
calculator ? The only thing I have found so far is Mortice Kern's Lex
and Yacc package which will be coming out this month with a Pascal
source code generator in addition to the C code generator.

Thanks in advance for any help.
