Basic PC routine linkage z/OS MVS Programming: Extended Addressability Guide SA23-1394-00 |

When a basic PC routine receives control, it must save the user's environment. Before returning control to the user, the PC routine must restore the user's environment. A basic PC routine that receives control in supervisor state can issue the PCLINK macro to save and to restore the user's environment. A basic PC routine that receives control in problem state must provide code that performs a function similar to the PCLINK macro. |
