Parameter in IEASYSxx (or supplied by the operator)

GRSRNL=  {aa        }
         {(aa,bb...)}
         {EXCLUDE   }

The two alphanumeric characters, represented by aa (or bb, and so forth), are appended to GRSRNL to form the name of the GRSRNLxx member(s). If GRSRNL=EXCLUDE is specified, no RNLs are to be used in the complex and all resources are treated as local.
