Enhance PASE APIs _ILECALL/_ILECALLX to Pass Operational Descriptors

Allow _ILECALL() and _ILECALLX() to pass operational descriptors when calling an ILE procedure, if they are not already capable of this, and provide documentation.

There is already a pointer field for the operational descriptor in the ILEarglist_base data structure that is used by these APIs. It's not clear if this is already functional, or just a placeholder. The usage is not documented.

Use Case:

Calling ILE procedures that rely on operational descriptors fails because _ILECALL() and _ILECALLX() don't pass the descriptors.

There should be a way for the caller to specify the descriptors. Otherwise, ILE procedures that rely on them (and possibly their callers) have to be rewritten in order to allow calls from PASE.

    IBM, please reconsider this request. Without it I'm not aware of any way that the IBM i XMLSERVICE or newer iService will be able to dynamically call RPG service programs that take full advantage of all the features of *NOPASS, *OMIT, and by value parameters. See

    The XMLSERVICE partially gets around this lack of functionality in "opm" mode by using a generic prototype that passes all parameters by reference. As far as I can tell it does not support passing any parameters by value. I believe the iService does something similar but it's unclear coming from C if that actually passes the operational descriptor that RPG needs to make %PARMS work properly.

    .Unfortunately, there are no plans to provide this function in the near future.
