in reply to confused: string and number comparison

Thank you for your answers. As lostjimmy and moritz already told the problem could be solved easily by doing string comparison. I think my problem was that perl turns a string which doesn't represent a number to zero for numerical comparison as johnqq stated.

    Note that this is not unique to Perl. Pretty much every language since C (and probably going back even further) will treat non-numeric strings as 0 when asked to treat them as numbers. Your problem is that you explicitly asked Perl to do a numeric comparison (by using ==) when that wasn't what you actually wanted.
