Issue:
We just upgraded OPS/MVS 12.3 to 13.0 for the first time on a test system. Everything looks good but we are seeing this warning/error at startup time:

OPS0041H OPS1250I SUBSYSTEM NAME 'OPSS' OPS0041H OPS1250I PARMLIB MEMBER NAME SUFFIX '00' OPS0041H CAOAlert RC=60 for:OPSPRM(SET,OPS3423,O)
OPS0041H OPS3423 - INVALID PRODUCT PARAMETER OPS0041H N/A
OPS0041H OPS1940E SYNTAX ERROR IN KEYWORD: TEXT
OPS0041H OPS1966E --- THE SINGLE LINE TEXT DATA PARAMETER MUST BE SPECIFIED
OPS0041H OPS1950E KEYWORD IS UNDEFINED: RC
OPS0041H OPS1950E KEYWORD IS UNDEFINED: FOR:OPSPRM

The value it does not like is pulled from the ABC.OPS.IBMPARMS(OPSSPA00) member and it's coded as:
z = OPSPRM_SET("OPS3423","O")

We set many other values like this. For some reason it does not like this one. Any ideas ?
Environment:
CA OPS/MVS 13.0
z/OS 2.2
Cause:
This particular message OPS3423I is not modifiable. It is issued by OPS code that runs at the CICS regions so it works differently from the normal OPS messages.
Resolution:
Remove the z = OPSPRM_SET("OPS3423","O") statement form the OPSSPA00 member.
