It isn't efficient to do "string1" . "string2" . "string3" . "stringN" Perl will, (in order of expression evaluation) allocate a new string to hold two of them, copy them to the new memory, then repeat this for the new string and the leftover string. As you can see, as N gets high, you're doing a -lot- of memory and copy work. That's what join() is for... cheers, b -- "it would be horrid to be robbed by the wrong kind of people" -archy Don Marquis, "the big bad wolf", 1935 ------------------------------------------------------- This SF.Net email is sponsored by: YOU BE THE JUDGE.
