Several languages, generally interpreters, provide an "execute" statement. You supply a string which contains a valid statement and it parses and executes that statement. Some older versions of BASIC do this. SNOBOL4 does this. LISP does this. Etc. Forget Pascal and C. I don't know of any interpreters for these languages that allow this. Of course, you could always write your own expression evaluator (you could use FLEX & BISON to generate the code for you) and link this into your program. *** Randy Hyde
