Re^3: How to avoid "Use of uninitialized value" with printf?

Please tell me how I could have presented my question better/more clearly so that I can ensure I do so in future?

:) Yeah, I probably should not have lead with that comment, not that I remember , nor can I even guess what I was referring to. Your question is very well presented (practically perfect). Mea culpa.

Are you clear on the issue of the warning?

Here is another way with Perl6::Form ( also documented at http://search.cpan.org/dist/Perl6-Doc/share/Exegesis/E07.pod ) based on demo_columns

the more verbose version

use Perl6::Form;
print form   {layout=>"across"},
'{:[{10}]:} {:[{10}]:} {:[{10}]:} {:[{10}]:} {:[{10}]:} {:[{10}]:} ',
\@UACS ,    \@UACS , \@UACS ,   \@UACS ,  \@UACS , \@UACS  ;

or the same thing using the repeat operator

    use Perl6::Form;
    print form   {layout=>"across"},
        '{:[{10}]:} ' x 6 ,
        ( \@UACS ) x 6;
[download]

Place either right after @UACS = sort(@UACS);, no splicing required, and @UACS remains full afterwards

Ahhh alrighty, thanks for clearing that up... still new to posting here, so doing my best to get it right... always best to make it easier on the folks you're asking for help as possible, is my philosophy :D Also, thanks for the additional options... unfortunately, I'm not able to check those out, as I'm currently stuck with 5.8.8. Thankfully I have some other suggestions to work with once I get some more time to work on this one :)	[reply]

Ahhh alrighty, thanks for clearing that up... After some more consideration, it was probably a fleeting thought I had that sounded vaguely humorous, so I typed it up to see how it lies (how it plays), but forgot to remove it after typing up the rest of my post unfortunately, I'm not able to check those out, as I'm currently stuck with 5.8.8. :) Well, Perl6::Form does run on 5.8.8 ( see http://matrix.cpantesters.org/?dist=Perl6-Form+0.04 ) and Yes, even you can use CPAN, but I understand, I still rely on sprintf even though Perl6::Form is much friendlier than perlform	[reply]
