sub dec2bin {

I don't see any "decimal" operations in there. That's just "num2bin". Take a number, and create a binary string from it.

In fact, this whole thread has made that common mistake. You aren't converting any "decimal" anywhere. Just because Perl knows how to take a string of decimal digits during parse to create a number internally doesn't mean your subroutine can deal with "decimal" numbers. It's Perl, not you.

update: Oooh, I missed the "bad use of $1" before as well. Never never never use $1 except in the condition of the previous match.
