 is_alpha(); is_numeric(); is_symbol();

They are amongst the most basic routines out there, however, they are still useful nonetheless.

You can grab the include/source from here: http://gushh.net/dev/?file=pb/ascii_helpers.pb

If you’re working on a Lexer, Parser, or similar… this will come in handy in case you don’t have it already.

Cheers.
