your sub swap can be written without $t:
sub swap { my ($i,$j) = @_; @a[$i,$j] = @a[$j,$i]; }

    lol, you bother to look upon this old piece of code :))

    heh, of course that your snippet is good, but a swap routine could be written even simpler:

    sub swap { reverse @_ }
    ... heh, it's not the case for that code thou, as the array is a global one :) cheers.

[perldigious]: A question since I'm ignorant of what's normal for database management... Do admins change column names a lot in databases?
[perldigious]: On occasion my scripts break, because they will do something that seems laregly pointless to me... like in this case, changing a column name from "ABC Category" to "ABC Category Override".
[perldigious]: Being the ignorant one, my initial reaction to that is, "that's sort of a dick move, a lot of people like me expect column names like that to stay the same, why the hell would you change them like that for seemingly no good reason?"
[perldigious]: Or is my irritation/ frustration well founded?
