pop ARRAY
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 @ARGV
array in the main program, and the @_
array in subroutines, just like shift
.
