in reply to Reg Expression Question

you could do something like that:

$okvalues = "0 20 34 23 5"; for($i = 1; $i < 100; $i++) { if($okvalues =~ m/$i/) { print "$i\n"; } }

    Did you try the code you suggested above? For output I get:

    2 3 4 5 20 23 34
    It incorrectly matches on 2,3 and 4. Now if you had modified your regex to be:
    $okvalues =~ m/\b$i\b/
    You wouldn't have that problem, because the \b assertion is only true between a word char and a non wordchar. This stops '3' from matching on '34'. Though, its still not a good idea to do it this way.
