Kind of. MVS turns some program interrupts into S0Cx abends. e.g. a data 
exception (PIC 7) becomes a S0C7. PIC 10 is commonly called a page fault. If 
the page is not allocated, MVS treats that similarly to a protection exception 
and issues a S0C4 abend.

That would be the Principles of Operation. The section on Program 
Interruptions. These are detected by the processor as instructions are executed.
