Only the names of exported procedures matter on signatures. Do a RTVBNDSRC on your service program and you will see that it is just a list of procedure names. As long as they don't change, neither will the signature. Parameters have nothing to do with it.

Subject: Stupdid NOOB Question about service program signatures

Just out of morbid curiosity:

On service programs created with EXPORT(*ALL),

I know that adding or removing an exposed function/procedure call changes the signature.

And I just added optional parameters to one exposed call, and found (to my surprise) that the signature didn't change.

Does anybody know what, other than adding or removing an exposed call, can change the signature? And what is guaranteed NOT to do so?
