Using the ENV parameter on IEAMSCHD

On the ENV parameter on IEAMSCHD, you can specify the following addressing environments for the SRB routine:
HOME
Specifies that the SRB routine is to receive control in the current home address space, and with PASID=SASID=HASID.
PRIMARY
Specifies that the SRB routine is to receive control in the current primary address space, with PASID=SASID=HASID.
FULLXM
Specifies that the SRB receives control with the scheduling program's current cross-memory environment. This means that when the SRB routine begins to run, it has the primary, home, and secondary address space of the scheduling program's at the time of the invocation of the IEAMSCHD macro. In addition, the SRB routine's DU-AL is a copy of the scheduling program's DU-AL as it exists when the scheduling program issues the IEAMSCHD macro, with the exception of any subspace entries in the scheduling program's DU-AL. The system does not copy subspace entries.
STOKEN
Specifies that the SRB routine is to receive control in the address space specified by the target STOKEN and with PASID=SASID=HASID.
