Re: How can I tell if my compiled RPG program has a handler?

Hi Ken

Actually, I found that QRNXUTIL was not included in every program, apparently only those that need its exported procedures. These include XML, JNI, memory, conversion stuff (I think), and others. I see XFOOT in there.

I thought I'd see the service program and procedure names in the object dump somewhere, but I didn't. Or I just missed it.

Hi Vern and Tom -

I think every RPG IV program, or close to it, has QRNXUTIL as a
service program.

It sounds like QRNX_GET_HANDLER is hiding the actual use of the
handler so that the handler is not included in any of the program's
reference information.

Bummer :(

DSPPGMREF shows the service programs in use - these are the same as are
listed in the *SRVPGM detail of DSPPGM - and they do not have anything
special - there are 4, QRNXIE, QRNXIO, QRNXUTIL, and QLEAWI - these are
always there, I believe, and have always been - they must comprise the
RPG engine. I've not probed more deeply to see what procedures are in
any of those, maybe there are new ones.

In a way, I think the point is, you should not need to know. Except that
now we might WANT to know.

I ran DMPOBJ against both kinds of programs - the handler-type had an
entry in a string directory of QRNX_GET_HANDLER - the regular one did
not have that. Now the regular one also had no IO, and this procedure is
in QRNXUTIL

A program with a handler has QRNXUTIL in the list of service programs
when you DSPPGM. A program without a handler might NOT have that service
program, not sure, since there are more things in there.

So that's enough treasure-hunting for now. If you feel you need this,
perhaps make a service call and ask to have it added - or use the DCR
approach or the COMMON requirement approach.

Ok, I have tried DSPPGM DSPOBJD and cannot see anything that shows me definitively that my RPG program will use a handler.

I'm not using handlers and I haven't been following the discussion
that closely so I don't know if they use bound calls or dynamic calls.
But if it is a bound call you should be able to see something in
DSPPGM or if it is a dynamic call you should be able to see something
in DSPPGMREF.
