pop
- pop
Pops and returns the last value of the array, shortening the array by one element. Has an effect similar to
$ARRAY[$#ARRAY--]
If there are no elements in the array, returns the undefined value (although this may happen at other times as well). If ARRAY is omitted, pops the
@ARGVarray in the main program, and the@_array in subroutines, just likeshift.
