Like other mapping directives, the executable directives REALIGN and REDISTRIBUTE also come in two forms (statement form and attribute form) but may not be combined with other attributes in a single directive. The RANGE and SHADOW attributes may be combined with other attributes in a single directive.
H801 combined-attribute-extended is ALIGN align-attribute-stuff
or DISTRIBUTE dist-attribute-stuff
or DIMENSION ( explicit-shape-spec-list )
or RANGE range-attr-stuff
or SHADOW shadow-attr-stuff
The SUBSET attribute is discussed in Section 9; the rest are discussed below.
