Hi Stephen -

IBM is the one who split the hair. Look at the documentation for APIs. Optional is a parameter that does not have to be passed. Omissible is a parameter which allows a null pointer (specified in RPG IV by *OMIT). A given parameter can optional, omissible, neither, or both.
If you pass a null pointer to IBM API for a parameter which is optional but not omissible, you're likely to get a MCH3601 error.
