Re^2: take 'n' array elements at a time

here's what I think I'll use: (the entire file is in @array)

my @i;

while (@array) {
        last if (scalar @array < 9);
        push @i, shift @array for 0 .. 8;
        print join ("\n", @i);
        print "\n------------------------------------------\n";
        @i = ();
        }

Thanks

Hi, Well that code is a step in the right direction. Couple things though, you can put the test inside the while loop instead of using "last". You can grab the first 9 items off of the array and delete them from the array in one operation using splice. This lets you avoid using the "@i" array. So: `my @array = map {$_ * 10} 1 .. 20; # test data while (@array > 8) { print join "\n", splice(@array,0,9); print "\n--------------------\n"; }` [download] Note that if the array isn't divisible by 9, the last few items will be silently ignored. If you'd rather see them, it's safe to just omit the "> 8".. splice will return whatever remains even though it's not the full 9 items.	[reply] [d/l]
