Re: Variables and Scope: The battle begins

If time is of the essence, why not utilise the depth of knowledge already in CPAN e.g. Parse::RecDescent, or has this become a problem that you now have to solve for yourself ?

Just a(nother:-) thought ...

A user level that continues to overstate my experience :-))

To expand on this great suggestion from Bloodnok, I found a nice tutorial for the parser. http://www.perl.com/pub/2001/06/13/recdecent.html From http://www.perlmonks.org/?node_id=108182 Sample code from the tutorial. `use strict; use warnings; use Parse::RecDescent; # Create and compile the source file my $parser = Parse::RecDescent->new ( q( startrule : day month /\d+/ day : "Sat" \| "Sun" \| "Mon" \| "Tue" \| "Wed" \| "Thu" \| "Fri +" month : "Jan" \| "Feb" \| "Mar" \| "Apr" \| "May" \| "Jun" \| "Jul" \| "Aug" \| "Sep" \| "Oct" \| "Nov" \| "Dec" ) ); # Test it on sample data print "Valid date\n" if $parser->startrule("Thu Mar 31"); print "Invalid date\n" unless $parser->startrule("Jun 31 2000");` [download]	[reply] [d/l]
