RE: Need help with a service program

There were NO parm changes. I commented out 1 line of code in the SCGETNVP
function.

Hi John,

I don't think finding the previous signature will help you if you changed
the parameter definitions.
As Buck said earlier, do a DSPPGM on one of the programs that is using the
service program.
Page through until you get to the *SRVPGM screen. It will show you a list
of service programs and the signature of each.
You will see what the signature used to be.
Specifying the old signature on your *PRV line will likely prevent the
signature violation messages but if the parameter definitions were changed,
your program will have problems.

I follow what you are saying but without rebinding our entire system,
how to I get it to find the *PRV signature?

John,

It looks to me that one or more parameter definitions changed.
Check a compile listing of the old version and compare it to a compile
listing of the new version.
The signature violation between a program and a service program is
similar to how a program gets a level check with a file that has changed.

No parm changes, just internal code changes.

Here is the error from the joblog,
Message . . . . : Program signature violation.
Cause . . . . . : The source program LOG03A specifies a signature

John,

Did you change the number of parameters or the size of any of the
parameters?
What error messages you are getting when you execute the service

program?

I'm not sure I understand your question. I modified code inside
of function SCGETNVP. I did not add a new function. Does that
answer your question?

Buck has the right suggestions. Question: Why is your export
*CURRENT and *PRV the same?

In the BND source, we have the following:

What piece did I miss?

If you could post the CRTSRVPGM command you used, we'd be able
to pinpoint it. Best guesses:

1) EXPORT(*ALL) instead of *SRCFILE
2) EXPORT(*SRCFILE) with the wrong SRCFILE() specified. Like
test vs production.

Further diagnostics:
Do a DSPSRVPGM to see what the current signature is.
Do a DSPPGM to see what signatures the calling programs expect.
