      NOTES      : On a SVC invocation of CMSSTOR data is passed to
            storage management via the USEUFLG in USAVE. This
            is done for the purpose of reentrancy. The CMSCALL
            expansion in CMSSTOR will set these bits in R15 and
            DMSITS will place them in USEUFLG. The STPLUFCO bit
            is used to determine if we should abend on error
            conditions. On BALR linkgae this is determined by
            the entry point invoked. The STPLBYLO bit is used
            to determine "where" to find the BYTES/DWORDS bit.
            On BALR linkage the BYTES/DWORDS bit is always bit
            32 of R1. The STPLUFBY is the SVC counterpart to
            bit 32 of R1 on a BALR. It may or may not be used
            depending upon the setting of STPLBYLO. If it is
            not used, STPLBYT in STPLFG2 will be used instead.
            This happens when BYTES/DWRODS was specified on the
            list form of the macro instead of the E form or
            standard form.
