case
- "UPPER" or "LOWER".

Example:
Specifying FOLD-COPY-NAME"UPPER" converts copybook names to upper case (also known as folding to upper case).

The Compiler also accepts the directive-name without hyphens; that is FOLDCOPYNAME.
The FOLD-COPY-NAME directive affects both text and library-names regardless of whether they are specified as user-defined words or literals.
