pop
Synopsis
pop @array
Treats an array like a stack, popping and returning
the last value of the array and shortening the array by one
element. If array is omitted, the
function pops @ARGV (in the
main program) or @_ (in
subroutines).
If there are no elements in the array, pop returns the undefined value. See
also push
and shift .
If you want to pop more than one element, use splice.
