Name : DMSSTPL Description: CMSSTOR parameter list macro DSECT : STPL Function : Mapping macro which maps the parameters generated by the CMSSTOR macro.

Hex Dec Type/Val Lng Label (dup) Comments ---- ---- --------- ---- -------------- -------- 0000 0 Structure STPL CMSSTOR parameter list macro 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. EQUATES used for mapping USEUFLG in USAVE on SVC invocation 1... ....
