NAME
remove - remove the last member of a list
SYNOPSIS
remove(lst)
TYPES
lst lvalue whose current value is a list
return any
DESCRIPTION
If lst has no members, remove(lst) returns the null value and does
not change lst.
If lst has n members where n > 0, remove(lst) returns the value of
lst[[n-1]] and deletes this value from the end of the lst, so that
lst now has n - 1 members and for 0 <= i < n - 1, lst[[i]] returns
what it would have returned before the remove operation.
EXAMPLE
; lst = list(2,"three")
list (2 elements, 2 nonzero):
[[0]] = 2
[[1]] = "three"
; remove(lst)
"three"
; print lst
list (1 elements, 1 nonzero):
[[0]] = 2
; remove(lst)
2
; print lst
list (0 elements, 0 nonzero)
; remove(lst)
; print lst
list (0 elements, 0 nonzero)
