in thread Need help comparing 4 dates

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;

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

[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?
[Corion]: perldigious: That seems to be more the export and likely it's the recipients of that export that like the titles changes
[Corion]: ... "changed"
[Corion]: I usually expect fixed header names, but am sometimes lenient in the order of columns. But changing the report titles often sounds to me as if you are not the sole consument of the export ;)
[shmem]: perldigious: as always - if it ain't broke, don't fix it. Ther must be a very compelling reason for changing column names in a database. Those are rare.
