Re: ILE RPG - Monitor for MCH3401 not working - With code of small sample programs -- RPG400-L

Well when you do an Extra you are branching out of the range of instructions bracketed by the Monitor code - so I guess I'm not that surprised although if this is indeed the case I would expect the docs to reflect it.

I'm guessing that if you move the monitor to the subr that it would catch the error.

As described in a previous thread (which i do not replicate here) i have a problem with MONITORing for MCH3401 - "can not resolve to object".

I now have 2 sample programs, stripped down to the bone, to demonstrate this.

Sample 1: Monitoring for MCH3401 works
//----------------------------------------------------------------------
dcl-s msg char(50);
dcl-s pgmname char(10) inz('PGMXYZ');
//----------------------------------------------------------------------
// Test for MCH3401 - Can not resolve to object - OK
//----------------------------------------------------------------------

monitor;
c call 'PGMABC'
c*
c eval msg = 'Normal end'
c msg dsply

on-error *PROGRAM;
msg = 'on-error *program. Status= ' + %char(%status());
dsply msg;
endmon;

*inlr = *on;

Sample 2: Monitoring for MCH3401 works NOT

//----------------------------------------------------------------------
dcl-s msg char(50);
dcl-s pgmname char(10) inz('PGMXYZ');
//----------------------------------------------------------------------
// Test for MCH3401 - Can not resolve to object - NOT ok
//----------------------------------------------------------------------

monitor;
exsr srmain;

on-error *PROGRAM;
msg = 'on-error *program. Status= ' + %char(%status());
dsply msg;
endmon;

*inlr = *on;
//----------------------------------------------------------------------
c*
c srmain begsr
c call 'PGMABC'
c*
c eval msg = 'Normal end'
c msg dsply
c*
c endsr
//----------------------------------------------------------------------

Slight difference: Sample2 uses EXSR, Sample1 does not.

Interestingly, other errors, eg. "MCH1210 - Decimal truncation" ARE handled by both samples.

Puzzling, isn't it?

Thanks for your ideas on this, cheers!
