I read the converse. in:
MVS Program Management: User's Guide and Reference
• The linkage editor processed the serially reusable (REUS),
reenterable (RENT) and refreshable (REFR) attributes as
separate and independent options. The binder, however,
treats them as a single, multivalued attribute with an
implied hierarchical relationship: “refreshable” implies
“reenterable” and “reenterable” implies “serially reusable”.
