For Lisp, just look for symbols that are immediately preceded by ( or #'. The tokens after ( are not always functions, since this is also used for constructing literal lists and for subforms of special operators (e.g. the variable names in LET bindings) but I think the ones that aren't functions will have low enough frequency that they won't impact the results. Perl would be harder, I think. For ordinary function calls you can look for a word followed by (, but built-in functions allow use without parentheses around the parameters. -- Barry Margolin, [EMAIL PROTECTED] Arlington, MA *** PLEASE post questions in newsgroups, not directly to me *** *** PLEASE don't copy me on replies, I'll read them in the group ***
