Re: Errors when calling programs

Jon,

nothing that will influence on pgm control, in this case, the pgm displays a message for me, just for test purpose.
I have been looking into CL-pgms, and the MONMSG statement, that gives me pgm control back, but first I have to answer the MCH-msg from the pgm that went wrong, manually, which I hoped I could avoid.


Mvh.

What are you doing in the error handling program?

I have made three testpgms:
TESTERR1 - main pgm - contains the error handling. Calls TESTERR3.
TESTERR3 - produces an error(MCH1202)
TESTERR2 - error handling pgm - works OK.

Calling TESTERR1 causes activation of the the error handler when
MCH1202 is returned from the call to TESTERR3.
I have hoped that control was given back to the next statement after
the call to TESTERR3, but this is not happening.
TESTERR1 ends with the message 'MCH1202 caused program TESTERR1 in
PF90 to end.'

So now I have made an error handling, but I still miss program
controll after the error. Is it impossible or can it be done in some
way?

Mark.

I'm almoust getting this to work now, but I need to know how many
parameters does the error handler use when it calls the error-
handling program(e.g. how many 01-levels does your MP08003 have in
LINKAGE SECTION?)

I have tried 1 and 5, but I still get ' Total parameters passed does
not match number required.'

You can set the cobol error handler so that any unmonitored error
will call a specified program. See example below where MP08003 is
our standard error handler;

WORKING-STORAGE SECTION.

COPY QUSEC OF QSYSINC-QLBLSRC.

01 WS01-ERROR-HANDLER-API.
05 WS01-EH-Y PIC S9(9) VALUE ZERO.
05 WS01-EH-PROGRAM PIC X(20) VALUE 'MP08003 *LIBL
'.
05 WS01-EH-SCOPE PIC X VALUE 'C'.
05 WS01-EH-LIBRARY PIC X(10).
05 WS01-EH-PREVIOUS PIC X(20).

COPY C4PYWS90.

PROCEDURE DIVISION.

CM00-CONTROL SECTION.
****************************************************************
* MAIN PROGRAM CONTROL *
****************************************************************
CM000-START.

* Set the error handler

MOVE 16 TO BYTES-PROVIDED OF QUS-EC.

* Call the API to register the exit program.

CALL 'QLRSETCE' USING WS01-EH-PROGRAM
WS01-EH-SCOPE
WS01-EH-LIBRARY
WS01-EH-PREVIOUS
QUS-EC.

* Check for an error

IF BYTES-AVAILABLE OF QUS-EC > ZERO
MOVE 'CBL-ErrHlr' TO WS99-FILE-NAME
MOVE 'Failed to set the Cobol error handler'
TO WS99-FILE-KEY
PERFORM 9990-IO-ERROR.

GOBACK.

CM999-EXIT.
EXIT.

Subject: [COBOL400-L] Errors when calling programs


Hi.

In a COBOL-program, I'm calling a Pascal-program(no source avalible!).
Now and again this Pascal-pgm returns a PSE-message which, of
course, makes my COBOL-pgm stop.

I want to take control over this in my COBOL-pgm, and issue a
programmed error message instead.

I can slightly remember someting about coding an 'on-error'-routine
in COBOL?
Or other ways to come around this, please?


Mvh.
