Thanks Bruce. I was hoping IBM api will check the address of the * parameter before using it. Sigh. . . .

No.
Parameters defined as being Omissible can be passed as a Null pointer, but that is it. Optional parameters are not the same as omissible. If you are passing a Null pointer for an optional parameter, and the API is working, I would say you are very lucky.

Is it safe to pass null pointer to any optional (*) parameter on any IBM
api and assume that IBM api will treat it as parameter not being passed?
