in reply to Check if one string is a substring of another.

To add to the next comments, if you want to see what string is longer, use length  length $st1 so you can check the longest one, as i understand you need that

#so you get something like this: my $index = 0; if ( lenght $str1 < length $str2 ) { $index= index $str2,str1; } else { $index= index $str1,str2; }
