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 to the corresponding pointee_name.
pointer_name contains the address of pointee_name.Must be a scalar variable name (but not a derived type).Cannot be: a constant, a name of a structure, an array, or a function.
Pointee of the corresponding pointer_name
Must be: a variable name, array declarator, or array name
If array_spec is present, it must be explicit shape, (constant or non-constant bounds), or assumed-size.
For example, we can 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.
We can also 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.
