<snip> PC routines are not supposed to issue SVCs as I understand it. However, WTO and WAIT work (for me, in my single user environment). Has the PC - no SVC restriction been relaxed, or opened up to particular SVC types? </snip>
The "supposed to" is not correct. No restriction has ever existed. What has always existed is that you can only (successfully) issue an SVC if in an environment where an SVC is allowed: task mode, enabled for interrupts, no locks held, no EUT FRRs, primary = home = secondary. If your PC target (or any routine for that matter) is in that environment, you can issue an SVC and it will make its way to the SVC target routine, otherwise you can't (the abend SVC can be considered an exception). The environments for issuing any service should be clearly documented as part of the documentation for that service.
