NAME
insert - insert one or more elements into a list at a given position
SYNOPSIS
insert(x, y, z_0, z_1, ...)
TYPES
x lvalue whose value is a list
y int
z_0, ... any
return null value
DESCRIPTION
If after evaluation of z_0, z_1, ..., x is a list with contents
(x_0, x_1, ..., x_y-1, x_y, ..., x_n-1), then after insert(),
x has contents (x_0, x_1, ..., x_y-1, z_0, z_1, ..., x_y, ..., x_n-1),
i.e. z_0, z_1, ... are inserted in order immediately before the
element with index y (so that z_0 is now x[[y]]), or if y = n,
after the last element x_n-1. An error occurs if y > n.
EXAMPLE
; A = list(2,3,4)
; print A
list (3 elements, 3 nonzero):
[[0]] = 2
[[1]] = 3
[[2]] = 4
; insert(A, 1, 5, 6)
; print A
list (5 elements, 5 nonzero):
[[0]] = 1
[[1]] = 5
[[2]] = 6
[[3]] = 3
[[4]] = 4
; insert(A, 2, remove(A))
; print A
list (5 elements, 5 nonzero):
[[0]] = 1
[[1]] = 5
[[2]] = 4
[[3]] = 6
[[4]] = 3
LIMITS
insert() can have at most 100 arguments
o <= y <= size(x)
LINK LIBRARY
none
