VarInsert
Insert an object into a container variable.
Syntax

VarInsert(X, i, x)

X
is a variable that is a linear container 
i
is an integer 
x
is a compatible object

If X
is an lvalue and a container, i
a valid index in a container of size #X + 1
, and x
a value that can be part of X
, then VarInsert(X, i x)
inserts x
at index i
in X
(so that i
becomes the index of x
in X
after the insertion). VarInsert
returns success
if successful.
This is the procedural version of insert
.
