Is there ever a "need" to write an SVC? Or to put it another way, is there sometimes a need to get OS services from a problem state program like in an SVC? And if so, are PC routines the new way?
Were once SVC's ok, and now they are not preferred? Just curious is all. Thanks!

If you were asking something like "I see an SVC issuance in a trace, what service was it?", then the diagnosis reference mentioned by Ray Overby can help. Peter Relson z/OS Core Technology Design
