ASC mode z/OS MVS Programming: Extended Addressability Guide SA23-1394-00 |

A stacking PC routine can receive control in either primary address space control (ASC) mode or in AR ASC mode. The ASC mode determines whether the PC routine can use ARs. AR ASC mode is required to use ARs. The ASCMODE parameter on the ETDEF macro determines the mode. The default is for the PC routine to receive control in primary ASC mode. |
