in reply to Re^3: array pop
in thread array pop

or more clearly, concisely and efficiently:

#! perl use strict; use warnings; my @array = ('a' .. 'e'); print 'Original @array contents: ', join(', ', @array), "\n"; my @popped = splice @array, 0, 3; print '@array now contains: ', join(', ', @array), "\n"; print 'The deleted elements: ', join(', ', @popped), "\n";

splice is your friend.

[perldigious]: I didn't want to tie up memory unecessarily basically, I wanted to "delete" it specifically to free it up, and wasn't sure I was even accomplishing that.
[stevieb]: perldigious You should start by writing some unit tests. That'll ensure current functionality doesn't break with changes.
[choroba]: unit tests++
[choroba]: The only problem you can't solve by adding more tests is the problem of having too many tests.
