I've always thought that a page fault in any operating system, including
z/OS, would generate an interrupt. The task requiring the missing page
would be put aside whilst RSM did the required I/O to the page datasets
(unless the page was already in memory - in expanded storage, or a
stolen page). However, I haven't been able to find any mention of this
interrupt (Principles of Operation mentions the six interrupt types),
and how it works.
Can anyone clear this up? Does a page fault generate an interrupt like a
program exception? If so, what sort? If not, what happens?
Thanks for your help.

Look at the z/Achitecture Reference Summary (descendent of the
original Green Card) under program interruption codes, especially
values x'10' and greater.
