Ah, that sheds some light! Since we have no (apparent) means of telling QZRUCLSP that certain parameters are optional but passed, it seems unlikely that it would be capable of guessing the correct means of passing same.

Probably a moot point, but is the "differently" part of your message a trade/business/compiler secret?

Thanks again. Now I feel more confident about this utility.

The open() API has optional parameters, prototyped in C by "..." and
prototyped in RPG by OPTIONS(*NOPASS). Parameters are passed
differently when the compiler knows that some of them are optional.
For
RPG, if you don't code OPTIONS(*NOPASS) on the optional parameters, the

API might interpret the optional parameters incorrectly even when they
are passed.

I'm just wondering if the other mechanisms to call open() are not able
to pass the optional parameters correctly.
