ECB=

Specifies the address of the ECB to be quick posted. If the ECB is currently waiting and you also specify SVC=YES on this macro, JES2 then requests that an MVS POST of the ECB be issued. If this keyword is not specified, an assembly error will occur.

CODE=

Specifies a 30-bit post code to be quick posted into the ECB. The default is 0.

SVC=

Specifies whether (YES) or not (NO) an MVS POST should be issued if the ECB is currently waiting (that is, the ECB wait bit is on). If SVC=NO is specified, no MVS POST is issued and a condition code is returned to the caller to signify whether the quick post was successful (CC=0) or unsuccessful (CC=1). The default is YES.

SVC= supports the new SYSTEM value. SVC=SYSTEM generates an MVS POST with LINKAGE=SYSTEM. SVC=YES generates an MVS POST with no other operands.

• JES2 main task, subtask, user address space, and HASPFSSM address space.
• $WAIT cannot occur.
