Actually, if you look really carefully, you'll see he's comparing it
successively to every integer between the initial value of $num (or 1 if it
wasn't set) and 100 -- but as he's never remembering these, all he'll get
out of this is whether the percentages are greater then one of these values
(which, if the loop starts at 1, it's more then likely they all will be!).
Mind you, if this is a snip of the real script and there's some output
making use of these values each time round the loop, this may actually be
what's required. ;)
Cheers!
