gtps1m3rSystem Macros

MONTC-Set Supervisor State (Monitor Mode)

Use this system macro to change the operating state of the central processing unit (CPU) from problem state to supervisor state. Supervisor state allows processing of privileged instructions such as set system mask (SSM) and start input/output (SIO). Use of this macro is restricted to utility type programs (such as disk copy and tape switch) that have special requirements for this state (system programming use only).
