What is $num going to be? A number? So how do you determine where that
number ends and where there shouldn't be another number in front of it...are
there any restrictions on the size of $num?
say $num is 51
then you're saying that you want to match
51::
but not 151::
however, what if $num is 151? see what i mean?
