There never truly was such a restriction (maybe if a PC-CP issued PCLINK?) The issue is the system state that the PC may cause. If it is a PC-SS then all services called by the routine must support PASN<>HASN. :>Also, a PC routine issuing a WAIT ecb,LINKAGE=SYSTEM also works. This WAIT issues a PC call itself, and PCs can call other PCs. :>Nonetheless, is issuing WAIT ecb,LINKAGE=SYSTEM from a PC playing with fire? BTW, Key zero is not required. If you are in a supported environment, no problem. To generalize, zOS recognizes various states that will cause it to refuse to perform some services. Among them: PASN<>HASN Secondary mode Home mode Physically disabled Locked EUT :>[This PC creates a couple of Name-Tokens to communicate with another address space, then WAITs.
