Re: Returning data with com.ibm.as400.access.ProgramCall

Yes it is. If you don't instantiate the object it's by default set to null.
It would be luck passing *OMIT to an RPG program if you did not instantiate
it.

You might not however need to create one for each parameter though. Maybe
just one for each type. I would need to look into a bit more to be sure on
that. I don't use program calls like this too often.

Is it really necessary to do this in order to get the data returned into
a java variable? I'm assuming that I need to create an AS400<whatever>
object to act as a template, so I create one for each bi-directional
parameter. Is that right, or am I just making a lot of work for myself?

int myPackedVar = 0;
AS400PackedDecimal myPackedParm = new AS400PackedDecimal(5, 0);
... snip ...
parms[5] = new ProgramParameter(
myPackedParm.toBytes(myPackedVar), 5);
if (myProgramCall.run()) {
... snip ...
if (parms[5].getOutputDataLength() > 0)
myPackedVar = Integer.parseInt(
myPackedParm.toObject(
parms[5].getOutputData()).toString());
}
}
