pop ARRAY

pop

Pops and returns the last value of the array, shortening the array by 1. Has a similar effect to

    $tmp = $ARRAY[$#ARRAY--];

If there are no elements in the array, returns the undefined value. If ARRAY is omitted, pops the @ARGV array in the main program, and the @_ array in subroutines, just like shift().
