Re: How to track the error messages in CL program for called RPGLE programs -- RPG400-L

I can safely say I would never have guessed techie21 was using DSPLY.
DSPLY sends *INFO message RNI5334, which is not an *ESCAPE -- *ESCAPE
being one of the message types (along with *NOTIFY and *STATUS) that can be
monitored (as has been mentioned in earlier responses by others). I'll
append an example shortly using *ESCAPE.

At a very quick glance, it looks like all you are doing is display an
error, and displaying an error does not SEND it in any fashion, so there
is nothing to monitor.

Hi,

Below program (between stars ***) is unnecessarily trying to execute pgm2
whereas why did it not understand that it already had received error when
it had called program 1 and that too was not sufficient it tried to
execute program 2 as well and finally when i called this program i ended

up

error from 1st program 1 and then when i pressed enter it displayed error
from second program pgm2 as well so it is not serving the purpose. just

to

explain in detail these customized errors from Program 1 and 2 are

getting

populated upon below such conditions:-
*******************************
DCL VAR(&GOOD) TYPE(*LGL)

CHGVAR VAR(&GOOD) VALUE('1')
CALL PGM(PGMA)
MONMSG MSGID(RXI0000 CPF0000 CPE0000 CPD0000 +
MCH0000) EXEC(DO)
CHGVAR VAR(&GOOD) VALUE('0')
ENDDO

IF COND(&GOOD) THEN(DO)
CALL PGM(PGMB)
ENDDO

***********************************
1) if fd less than 0 (fd used here to open some XML file located in some
directory )
dsply ('error message')

2) if %found(file name)
then assign some values to some fields

else

dsply ('some other error message')

3) if not %eof(file name)

do something

else

dsply ('some different error message')

4)Monitor;
vCommand = 'ADDLIBLE LIB(LIBHTTP) POSITION(*LAST)';
QCMDEXC(vCommand : %Len(%Trim(vCommand)) );
On-Error;
Dsply 'Unable to add library LIBHTTP ';
*InLr = *On;
return;

so these are just some examples as shown above similarly there are many
error messages which are invoked if certain conditions inside these RPGLE
programs (program1 & Program2) fail.
so objective is that whenever this main driver CL program executes these
RPGLE programs it should be able
to understand what error each program invoked and whenever it traps any
such error either in program1 or in program 2
it must be able to tell clearly with error message description that this
error occured in this program and condition is
it should execute program2 only if program1 got executed successfully and
in case later on program 2 gives some error
then it should clearly tell that error occured in program 2 and this is

the

error description and then after executing
this CL program let's say program 2 gave some error and when we called

this

CL program it showed particular error on program2 and
once we do F1 on that error message then we should be in condition to

know

exactly at which line at which program error occured.

Thanks much...

actually main thing is this logical indicator fails when i tried this
advised program and unnecessarily going to pgm2 evenif pgm1 had some
customized error messages like 'record not found'
'unable to open file'...etc.
means it has some if else conditions based on these conditions these

rpgle

programs throw these customized error messages.
how to use this &errorcode where to put it i mean any example for this
please?

I gave you this before and it works as long as these customized
error messages you're talking about have message ids and they are

*ESCAPE

messages. In this case, add these message ids to the MONMSG below.

DCL VAR(&GOOD) TYPE(*LGL)

CHGVAR VAR(&GOOD) VALUE('1')
CALL PGM(PGMA)
MONMSG MSGID(RXI0000 CPF0000 CPE0000 CPD0000 +
MCH0000) EXEC(DO)
CHGVAR VAR(&GOOD) VALUE('0')
ENDDO

IF COND(&GOOD) THEN(DO)
CALL PGM(PGMB)
ENDDO

Sincerely,

Dave Clark
