Is there a Stack in perl and im just not finding it in books?
If there isn't a Stack, is the best way to make one using an Array?

Hi,
You can use built-in functions push and pop on arrays to get the behaviour of a stack.
The following code may help you
my @stack; #its an array
#push some elements
push @stack,1;
push @stack,2;
#get the length of the stack
$len=$#stack+1;
#pop the elements
for ($i=0;$i<$len;$i++) {
$top = pop @stack;
print $top;
}
#now the stack is empty
