in reply to Misprinting combinations / iterator

The $combination variable returned by the iterator is an array reference, so you need to de-reference it in order to print. The following will print each combination on a line, with each element separated by a tab character:
print $output join("\t",@{$combination}) . "\n";
The @{ } construct is what de-references the array reference

[stevieb]: Damn... just wasted two hours wondering why num 23 wasn't setting bit 5 in a register. I was working on the decimal, but the register holds BCD numbers. Sigh.
