make_array(++Array)

Creates the untyped array or global variable Array.
Array
Atom or ground compound term with integer arguments.

This built-in predicate is obsolete!

Description

If Array is an Atom, a global variable (visible from all modules where a local one of the same name is not defined) is created. Its value is initialised to a free variable.

If Array is a compound term, a global array of type prolog is created, its dimension is the arity of the term Array and the size of each dimension is specified by the corresponding argument of the term Array. The elements of arrays of type prolog are initialised to free variables.

Note make_array(A) is equivalent to make_array(A, prolog).

Modes and Determinism

Modules

This predicate is sensitive to its module context (tool predicate, see @/2).

Exceptions

(4) instantiation fault
Array is not ground.
(5) type error
Array is not an atom or structure with integer arguments.
(6) out of range
The ground structure Array has arguments that are integers not greater than 0.
(42) redefining an existing array
An array with the same name and dimension as Array already exists.

Examples

Success:
      make_array(a(4)).
      make_array(b(2,3)).
      make_array(a(4)), make_array(a(4,1)).
      make_array(a), make_array(a(1)).

Error:
      make_array(X).                        (Error 4).
      make_array(a(6.0)).                   (Error 5).
      make_array(a(0)).                     (Error 6).
      make_array(a(-2)).                    (Error 6).
      make_array(a(4)), make_array(a(5)).   (Error 42).
