Emeka,
Yes in a way, but the point am making here is that
one can also pass hash into a subroutine. Context is everything in Perl!
Caution has to be taken however when converting array into hash. Hash
elements must be even in number, whereas odd numbers of elements could be in
array, one is passin

As you can see, the answer is a bit more complex than it would seem. If you
go by what ref() says, there 4+. If you go by their fundamental structure
there are just scalar they are interpolated into whatever it should be.
That said, when you deal with most things, using references are the best. It
Hi Rajeev,
with the link you provided, the statement "In Perl, you can pass only one
kind of argument to a subroutine: a scalar... a pointer (sort of)." was made
