RE: LDA Not Getting Retrieved

True. Which is what I was trying to say in my second paragraph. I just
FUBARed it.

Jerry,
If you are going to use the LDA and not define as UDS, you need to lock the
data
area on you IN command in order to update it on the OUT.
ie;
*LOCK  IN LDA
OUT   LDA

Yeah, I guess I should change my ways and use parms more (if only so I can
quite imagining Barbara going "Tsk, tsk" somewhere).

Further testing, as well as a deeper reading of the RPG ILE Reference
manual, exposed the fact that Terry, who suggested using UDS on the D-spec,
was correct.  With just a DS and DtaAra(*LDA), one needs the IN and OUT
op-codes to handle the data area.

Just a suggestion, but why not pass the value of  L$CNCL as a parm from your
CL
to the RPG.
When you set the value in your RPG program, it will be returned to the CL
and
you can test it the same way.
This removes the need for the LDA in both programs.

Hi Jerry,

Perhaps, just an oversight, but are you sure you do an OUT *LDA after
setting L$CNCL and prior to calling IVS002?

I am trying to use a byte in the LDA to tell a CL program (type CLP; i.e.,
OPM) that the RPG IV program, which the CL called, told it to abort the
rest
of the CL.  Inside of the RPG IV program the LDA is defined via a /copy
statement  as:



D                DS                  DtaAra(*LDA)

D L$CNCL                482    482a



The relevant parts of the CL program are:



CALL      PGM(IVS002)



RTVDTAARA  DTAARA(*LDA (482 1)) RTNVAR(&CANCEL)

IF        COND(&CANCEL *EQ 'Y') THEN(DO)

  SNDPGMMSG  MSGID(GEN9999) MSGF(ANKLIB/ANKMSGS)

            TOPGMQ(*EXT) MSGTYPE(*STATUS)

  DLYJOB    DLY(3)

  RETURN

ENDDO



I have debugged IVS002 and verified that, when F3 is pressed, the function
key is recognized and that L$CNCL does, indeed, equal Y.  I have, also,
debugged the CL program and verified that after the RTVDTAARA command that
&CANCEL equals *Blanks.



I have done this numerous times in the past without a problem.  The only
difference, that I can put my finger on right now, is that previously I

was

at V5R3 and R4.  This program is at V5R1.



The purpose for using the LDA is to be able to allow the CL to ascertain
that the user wanted to abort the rest of the CL (in this case a simple
select [IVS002] and, if F3 is not pressed, a report [IVR002]).  A named
data
area will not do, because the report could be invoked simultaneously by
more
than one [1] user; at least I don't think so.



If anyone has a better method for making the determination that F3 was
pressed in IVS002 before proceeding to IVR002, I'd certainly be willing to
hear about it.  In the meantime, is there some reason that the CL cannot
retrieve the value of L$CNCL as set by IVS002?  I did check the RPG
Reference manual, and it did not yield anything.  I compared the steps and
code that I used to a similar process that I know worked in V5R4; no
differences.
