in thread Need help comparing 4 dates

The reason for asking was this bit of the error message you posted:  <DATA> line 2.

Did you get more than one copy of the error message (on different lines)?

Another possibility, though I can't see how it would arise, is that you have and old version of Date::Manip?

    I do have an older version (5.54)..I'll install 5.56 and see if that fixes it.

    The warning does repeat for multiple lines...a lot. I was going to capture them in a file and then grep the count, but only the output displayed below was captured in the file

    Also, what is interesting is that the output contains a blank line between the header and result set even though there is no blank line after __DATA__

    EVENT   JIM     BOB     SAM     JACK

PTRED   4       3       2       1
RED     3       1       2       4
INT     3       4       2       1
PTRED   2       1       4       3
RED     2       1       3       4
INT     4       3       1       2

    Actually, nevermind about the blank line in the result set. I see that yours has it also. Must come from the "+1" in the print.

      Erm, no. The header line, and the following blank line in the output, are printed by this line: 

      print scalar <DATA>;

      It has one newline because I didn't chomp it. And the second, because I have -l on the hashbang line: 

      #! perl -slw

      Which has the affect of automatically adding "\n" to the end of every print line.

      The +1 in this line:

          print join "\t", $label, map $_+1, sort{
        $order[ $a ] <=> $order[ $b ]
    } 0 .. $#order;

      [download]

      converts the numbers 0 .. 3 used to index the array while sorting. into the numbers 1 .. 4 used for your desired output.
