variables

vikee has asked for the wisdom of the Perl Monks concerning the following question:

Hello,

simple question again: I want to create arrays in a foreach cycle but always something wrong:

$i = 0;
foreach $tab (@tabs) {
    j = 0;
    foreach $frnum (@FRs) {
        $tmp = $tab->Checkbutton(-text => $frnum,
                    -variable => \@tab$i[$j],
                    -command => sub { }
                )->pack(-side => 'top', -anchor => 'nw');
        $j++;
    }
    i++;
}

I want to create for each tab an array called tab1, tab2, etc that this array could contain all the checkbox variables.

help me, I'm very new. thnaks

You probably want to use: `-variable => \$tab[$i][$j]` [download] See perldata, perllol, and perldsc for more info on perl arrays (and other data structures). brad	[reply] [d/l]
