Cobol V5/6: Additional RULES suboption (NO)UNREF to flag unreferenced variables

One available solution for storage optimization is compile option STGOPT.
With this option the compiler discards unreferenced data items.

Instead of using compiler option STGOPT, we would prefer to eliminate unused data items
from source for better maintenance.

For this purpose a new RULES OPTION i.e. NOUNREF like in PLI would be helpful to point
out unused data items best with SUBOPTIONs ALL/SOURCE to control the handling of copy books.

Enterprise PL/I for z/OS Programming Guide 5.1:
"Specifying NOUNREF causes the compiler to flag any level-1 AUTOMATIC variable that is not referenced and that, if it is a structure or union, contains no subelement that is referenced. NOUNREF ignores variables with names that start with any of the following prefixes: DSN, DFH, EYU, and SQL."
