    So I'll have the ID # and a list of other ID #'s and I need to know if it's the smallest.

    That code is very confusing. Sorta like taking a flight from NY to LA by via Johannesburg and Perth. Why not just grab the smallest element of the list?

    use List::Util qw(min);

    if ( $id_number == min(@ids) )

    If you needed to avoid List::Util for some odd reason, I don't know why you would sort a list, reverse it and take the last element (in a most convoluted fashion) when you could just:

    if ( $id_number == (reverse sort @ids)[-1] )

    Or even more clearly:

    if ( $id_number == (sort @ids)[0] )
    • *nod* - agreed. See prev. comment - I simply wanted to apply what Cees taught me about scalarizing a list.

      Hmmm -- maybe this won't even see the light of day in my import script now. ;)
