Hi,

The code below is supposed to find the quantity/number of records that 25% represents in array @total and then select that number of records from array @sub randomly. Is this code alright?

$n = @total * .25;
$m = @sub;
@select = grep rand($m--)<$n?$n--:0, @sub;

I tested this on my side and it 'seems' to work fine. However, I want to be sure that I'm doing the right thing here.

Thanks,
Ralph.
