You were lucky; I've encountered far too many auditors who did not know what to 
look for and at best could follow a cookbook, and not always an appropriate 
cookbook. OTOH, a good auditor is a resource to be treasured.

I found this out by trial and error, and one level 1 support tech actually told 
me what you had said, not documented that way but then why would it .
Auditors of past, on the mainframe knew what to look for, knew where to look 
and understood parmlib and the values, now... not so much

<snip>
have in a shared parmlib IEASYS00 member OPI=NO
...
IEASYS LIST = (00,SA,20) (OP)
...
Mark's IPLINFO rexx shows
OPI=YES, Default
</snip>

The OPI setting is reset as each IEASYSxx is processed, and it defaults to
"YES".
So as each IEASYSxx member is processed, its OPI value is set as the
single OPI value that can be displayed after IPL. That is what is going
on. That has little to do with what OPI=xxx values were in effect for the
set of IEASYSxx members.

So yes if for some reason you want the display to show "NO" then you will
need OPI=NO in the last IEASYSxx. But that provides no useful information
for cases where you have multiple IEASYSxx's. Only by manual examination
can you see that all IEASYSxx's had OPI=NO in effect (and that no
individual IEASYSxx parameter had specified OPI).

If your audit wants to know that there was no use of OPI=YES (or OPI for
an individual parameter), you're not going to be have a happy auditor
unless they're willing to examine all the IEASYSxx's that were identified
as being used.
