Newbie queston on Perl and lex.

[somedeveloper]

Hi,

1. If my needs are only lexical scanning (and not compiler- and
interpretor-writing), and
2. If I'm proficient in Perl and Perl regular expressions,

would I ever need to learn a tool such as f/lex? Is there anything
that Perl REs cannot do easily/elegantly which f/lex can, for example?

Many thanks,
Some Developer.

I don't have the slightest idea. But I know an article that you may be
interested in:

Michele, thanks! The article did give me an idea of what I guess I was
trying to know.

PS: Ran your signature program... it's cool! Hopefully, I'll be able
to decode it in near future... when I'm more comfortable with the
language.
