Subset/Superset PRMOD Names

Two of the operands allow subsetting. For example, the module name IJDFCPIW is a superset of the module names IJDFCZIW and IJDFZZIW.
Note: The IBM-supplied modules were assembled without TRC=YES. You can reassemble them with TRC=YES to support 3800 table reference characters. Although the code generated for a module that is assembled with TRC=YES is different from the code that is generated for a module with TRC=NO, the module name is the same. If some, but not all PRMOD logic modules are reassembled this way, subsetting or supersetting might not work.
