Re: Can you have nested MONITOR statements? -- RPG400-L

In the RPG program the status are numbers. I think I missed somethig.
Is the subrutine sending the error?
Or is the program?

Can you monitor in the subrutine?

How can you create user defined statuses, send and retrieve them?
What if I have message Id 'MSG4711' and 'ERR4711'?

Why not:

 Monitor;
   Called(Parm1: Parm2);
 On-Error 4711;
       //Do Something
 On-Error 4712;
        //Do Something else;
 On-Error;
        SndEscMsg(SDSMsgId);
 EndMon;

Hi,

May be I misunderstood. But isn't this already available?

I solved this by sending escape messages (with a wrapper procecude
around
QMHSNDPM) to the previous callstack. The message id and the complete

message

text (atleast the first 70 characters) can be retrieved from the program
status data structure. In this way I can handle different MSGIDs in
different ways.

Example:
Called Procedure:
SendEscMsg('MSG4711');

Caller
Monitor;
  Called(Parm1: Parm2);
On-Error;
  Select;
  When SDSMsgId = 'MSG4711';
       //Do Something
  When SDSMsgId = 'MSG4712';
       //Do Something else;
  Other;
       SndEscMsg(SDSMsgId);
  EndSL;
EndMon;

Instead of defining a "block of status codes" for user-written
applications, I'd prefer to see MONITOR able to monitor for message IDs,
similar to the way CL's MONMSG is able to check for msgids.

That way, a throw() routine is nothing more than a wrapper for QMHSNDPM
-- it just sends an escape message from a *MSGF...   Users can create
and add message descriptions to their own message files as they see fit.

With MONITOR able to trap specific error messages, you'd trap for
USR0001 (or whatever) to catch the user's errors.   Plus, you'd be able
to use it with IBM APIs and CL commands that already return escape
messages with message ids.

Are you listening Barbara? <grin> - I do think we need support for aan RPG implementation of throw(). The problem right now is that whenyou throw an exception you still need some kind of return code in thebackground because RPG only signals a generic code to Monitor. Thereare hundreds of available status codes - it would be nice if a block
was allocated as User Defined and the throw op-code allowed you to
specify a specific status code that you were signaling.  If I had that
I'd use it for most everything.
