math problem
Are you working in C? In forums like the DDJFORUM or the CLMFORUM, you should
be able to find straight C code for writing your own math parser and evaluator.
It's a relatively complex process. Or maybe check the Borland forums… I
know their C compilers come with a demo spreadsheet that includes an expression
parser. Hypercard makes it easier because it's interpreted, not compiled.
It's not hard for it to give the programmer an option to interpret a string,
when Hypercard is doing that for the entire rest of the script.
