PrimePSA (EXEC PGM=IGVDGNPP) is not documented and is not supported. And that
is not likely to change. It certainly won't change without a formal request for
the functionality it provides. You can do what you want, and I don't recall it
ever not doing what it intends to do, but do not expect assistance from IBM
Service with respect to anything within your system that goes awry due to that
(be it IBM code or otherwise). Running it usually exposes problems but can,
actually, hide a problem depending on the instructions that are unintentionally
referencing the first page.

The V= parameter (in the example V='50404143,AAAAAAAA,55555555,FFFFFF7F')
identifies a group of values that are cycled through.
Martin Ward's example of erroneous reference to page 0 that a scan can find (I
removed the "nnnn" and "mmmmm")
CLC 0(R1),field
field DC C'9'
is also flagged by *PROCESS FLAG(PAGE0)
which had been mentioned. Many would think that it best to have such problems
exposed by the assembly itself.
