OK, there are limitations.

But ProgramCall object don't allow return values either.

PCML can do everything a ProgramCall can do (because ProgramCallDocument wraps ProgramCall) but is easier for non-IBM i developers to use, because they just set & get values using a structured naming scheme.

As a developer familiar with IBM i, I find PCML calls to be much easier to understand ... I don't have to be aware of all the parameter sizes & positions, I just define the PCML document once (or, even better, let the compiler generate it for me), load the document, set the variables, and make the call.


ProgrammCall, doesn't allow return values, that's true, but SRVPGMS (and DDLs) too) have return parms and so you would have diffrent ways to call a PGM and a SRVPGM. Thinling in java, you would use some beans (aka Pojos) to wrap structures. I prefern (and recommand) to encapsulate these structure as parms in objects looking from one side as Pojos and from the other side as a DS (I call this Pords2Pojo = PlainOldDataStructure to PlainOldJavaObject). I'm using this frequently in ArdGate to seperate the RPG looking code from Javacode.


@Pete: what about your eMail adress?
