pop ARRAY

pop

Pops and returns the last value of the array, shortening the array by one element.

Returns the undefined value if the array is empty, although this may also happen at other times. If ARRAY is omitted, pops the @ARGV array in the main program, but the @_ array in subroutines, just like shift.
