The Cray POINTER statement has the following format:

POINTER  ( pointer_name, pointee_name [array_spec] ), ...

Where pointer_name, pointee_name, and array_spec are as follows:

pointer_name

Pointer to the corresponding pointee_name.

pointer_name contains the address of pointee_name.

Must be: a scalar variable name (but not a structure)

Cannot be: a constant, a name of a structure, an array, or a

function

pointee_name

Pointee of the corresponding pointer_name

Must be: a variable name, array declarator, or array name

array_spec

If array_spec is present, it must be explicit shape, (constant or nonconstant bounds), or assumed-size.

Example: Declare Cray pointers to two pointees.

	POINTER ( p, b ),  ( q, c )

The above example declares Cray pointer p and its pointee b, and Cray pointer q and its pointee c.

Example: Declare a Cray pointer to an array.

	 POINTER ( ix, x(n, 0:m) )

The above example declares Cray pointer ix and its pointee x; and declares x to be an array of dimensions n by m-1.
