![]() PC routines z/OS MVS Programming: Extended Addressability Guide SA23-1394-00 |
|
To provide a service, the service provider supplies a PC routine and uses MVS™ macros to make the PC routine available to the address space of the user who needs the service. A service provider can make a PC routine available to users in all address spaces or to users in selected address spaces only. Before a user can invoke a PC routine, however, the user also needs a PC number, which the service provider must provide. Each PC number identifies a specific PC routine. ![]() ![]() ![]() |
