By way of explanation, this builds a long regexp through basic string interpolation like the following: `/^(?:1950\|1951\|1952\|1953\|...\|2049\|2050)$/;` [download] After generating a regex like that, if you will be using it often, you might want to optimize it for common prefixes or suffixes. `use Regex::PreSuf; my $re = presuf(1950..2050);` [download] -- `[ e d @ h a l l e y . c c ]`	[reply] [d/l] [select]

If the OP wanted something optimized, he wouldn't have used a regex to begin with. Abigail	[reply]
