in reply to Range Issue with RegEx

Or create a hash lookup for your range and then compare it to the numbers. This is probably the best method if your data file is very large and/or your range is large.

$h{$_} = () for (500, 501, 502, 531, 532); while (<DATA>) { chomp; print "$_\n" if exists $h{$_}; } __DATA__ 500 501 502 503 504 508 522 531 532 505
