As part of my project at University, Im investigating RegEx matching
in Perl and Lex, comparing and contrasting. I was wondering if anyone
out there could refer me to papers or URL's that describe the
mechanisms that Lex uses in RegEx matching.

Any help would be greatly appreciated!

Best Regards,

[There's the man page and there's the source code. Don't know of any
doc beyond that. Lex builds a full DFA and runs the state machine,
unlike most other matchers that just make a NFA. -John]
