}
else {
# It's not a reference
}

hi,
what i want to proove is...supposer that i assign an
array @a = (1,2); and then i define another array @b
which is equal to @a.I have to proove that this is
done by assigning a copy of array @a to @b rather than
by reference.
Can you help me do that...i am bit confused ..
thanks a lot..
