I'd say that the questions are not precisely-enough posed. <snip> 1)Can a Problem Program (Key 8) attach a Subtask that is authorized ? 2)Can a Problem Program attach a subtask (with the DCB parameter) that is authorized ? The dcb is not in the steplib concatenation. 3)Can a Problem Program invoke a Non Space Switching PC routine to Attach a Subtask that is Authorized ? </snip>
What is "authorized" here? APF-authorized? Supervisor state? System key? A problem key supervisor state user could certainly attach a subtask that is supervisor state. An authorized (state, key or APF) issuer of ATTACH can ATTACH a subtask with pretty much any attribute it wants regarding state or key. Changing the APF authorization is not part of the programming interface. So for #1: sure. But that probably is not what is being asked. A problem state problem key non-APF-authorized task cannot attach a subtask that is other than that same level of authorization. For #2, similarly above. "not in the steplib concatenation" is not relevant. Steplib has no special connotation. A concatenation is a concatenation. LNKLST has a special connotation depending on the LNKAUTH system parameter. Nor does the APF state change regardless of whether the module is AC=1, regardless of whether the module is located from an APF-authorized concatenation. For #3, sure, if that PC routine results in the ATTACH being issued in supervisor state or system key.
