guideline

Do not use a representation clause to specify number of storage units.

rationale

The meaning of the 'Storage_Size attribute is ambiguous; specifying a particular value will not improve portability. It may or may not include space allocated for parameters, data, etc. Save the use of this feature for designs that must depend on a particular vendor's implementation.

notes

During a porting activity, it can be assumed that any occurrence of storage specification indicates an implementation dependency that must be redesigned.
