<=> should probably still work, because when evaluating a string as a number, Perl will evaluate up to the first character that doesn't look like part of a number. so "1234 x5" evalutates as the number 1234 (stops at the space char). If the number you want to sort by is not at the beginning of the string (leading blanks are OK), you have to write a more elaborate comparison routine. Have you tried just using <=>? If it doesn't work for you, post a specific example that illustrates the problem. > Sorry if this is a dumb question. Nah, it's a good question. Anyway, we get spanked if we even look sideways at somebody (speaking as one who's been spanked) :~) -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
