Variables Referenced in a Region but not in a Construct

Local variables declared in called routines in the region and that have the SAVE attribute, or that are data initialized, are shared unless they appear as arguments in a threadprivate directive.

Variables belonging to common blocks, or accessed by host or use association, and referenced in called routines in the region are shared unless they appear as arguments in a threadprivate directive.

Dummy arguments of called routines in the region that have the VALUE attribute are private.

A dummy argument of a called routine in the region that does not have the VALUE attribute is private if the associated actual argument is not shared.

A dummy argument of a called routine in the region that does not have the VALUE attribute is shared if the actual argument is shared and it is a scalar variable, structure, an array that is not a pointer or assumed-shape array, or a simply contiguous array section. Otherwise, the data-sharing attribute of the dummy argument is implementation deﬁned if the associated actual argument is shared.

Cray pointees have the same data-sharing attribute as the storage with which their Cray pointers are associated. Cray pointer support has been deprecated.

Implied-do indices, DO CONCURRENT indices, FORALL indices, and other local variables declared in called routines in the region are private.
