pop
Synopsis
pop @array
Description
Treats an array like a stack, popping
and returning the last value of the array, 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.
