adding a count before the limit?

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

not sure how to title this post.

the code below gives the count i need, but i'm having trouble printing the count where i need it, which is in the third position. i've tried splice and other things, but i have to do that before the last statement, so i get a wrong count.

my $accounts_by_id = {};
for (@accounts) {
   my($id, $rest) = split /,/, $_, 2;
    $accounts_by_id->{$id}->{info} = $rest;
}
for (@purchases) {
    my($id, $rest) = split /,/, $_, 2;
    push @{$accounts_by_id->{$id}->{purchases}}, $rest;
}
for (@accounts) {
    my($id, $rest) = split /,/, $_, 2;
    {
        my @five = splice
               @{$accounts_by_id->{$id}->{purchases}}, 0, 5;
        last unless @five;

#I NEED TO COUNT AND PRINT THE NUMBER OF ITEMS IN @FIVE HERE BUT I HAV
+EN'T INCREMENTED THE COUNTER YET
print "$id,$accounts_by_id->{$id}->{info},",
             join(',', @five), "\n";
$count =0;
foreach $id(@five){
$count ++;
}
#THIS GIVES ME THE RIGHT COUNT
print "count is: $count endcount";
print "<br>";
        redo if @five == 5;
    }
}

Then why don't you increment the counter first? Or, just do `my $count = @five;` In general, if you think something isn't in Perl, try it out, because it usually is. :-) "What is the sound of Perl? Is it not the sound of a wall that people have stopped banging their heads against?"	[reply] [d/l]

Just to clarify dragonchild's second suggestion: does this do what you need? `my $count = @five; print "$id,$accounts_by_id->{$id}{info},$count", join(',', @five), "\n";` [download] the lowliest monk	[reply] [d/l]

because then i get a count of say, 12 on each line that matches instead of 5 and 5 and 2. i only get the right count after the join. any clues for the clueless? Malaga	[reply]
