Hi,

I wrote some pseudo code and when Perl-izing it I discovered I can't seem to do what I had planned the way I had planned. I do not use Pearl often so I was wondering if you could tell me how you usually save values in a two-dimensional array as I have not found any examples.

Below is the partly Perl-ized portion of code where I had expected to loop through the two dimensions of an array called @summary, the first dimension would represent the week-of-the-month and the second the day-of-the-week. The value to be put in each location was the total number of orders placed on a particular day (the %total_opd hash) with each row across showing the day of the week and the columns were how many weeks the month spanned (a month can span 4, 5, or 6 weeks). Below is kind of what the output would look like: 0,0 means week 1 (partials count) and the second 0 is for Sunday. Next would be 0,1 for week 1, day 1=Monday.

There may or may not still be other bugs but the real issue is how would I stuff the array?

Thanks.

my $numWks = (($num_days - ( 7 - $firstDOW_curMonth )) / 7 ) + 1;
if ( (($num_days - ( 7 - $firstDOW_curMonth )) % 7 ) ) { $numWks++; }

my @summary[$numWks][7];   # !!! uh-oh this does not Perl-ize !!!

# init the blank portion of $summary[][] if there is one
my $temp = 0;
while ( $temp < $firstDOW_curMonth ) {
    $summary[0][$temp++] = "--";
}
my $wktotal;
my $count=1;
my $firstDOW = $firstDOW_curMonth;
for ( my $wk = 0; $wk < $numwks; $wk++ ) {
    $wktotal = 0;
    for ( my $dw = $firstDOW; $dw < 7; $dw++ ) {
        $summary[$wk][$dw] += $total_opd{$count};
        $wktotal += $total_opd{$count};
        last if ($count++ == $num_days);
    }
    $firstDOW = 0;
    $summary[$wk][$7] = $wktotal;
    last if ($count > $num_days);
}
