Re: return() and retain job log

Hi Patrik,
I'm not a C programmer so I can't give an example in C, I just follow this
forum as every so often there's some interesting uses of APIs. 
What I've done below is provide the values for each of the required
parameters that I would use.
HTH

Required Parameters Group:
1 	Message identifier 	Input 	Char(7) 
'CPF9898'
2 	Qualified message file name 	Input 	Char(20)
'QCPFMSG    *LIBL'
3 	Message data or immediate text 	Input 	Char(*)
'any text you want to describe the error'  (not null terminated)
4 	Length of message data or immediate text 	Input 	Binary(4)
Length of above string
5 	Message type 	Input 	Char(10)
'*ESCAPE'
6 	Call stack entry 	Input 	Char(*) or Pointer
'*PGMBDY'
Note: I use this value so it will jump over all intermediate procedures to
the calling PGM boundary.
7 	Call stack counter 	Input 	Binary(4)
1
8 	Message key 	Output 	Char(4)
A 4 char variable to receive the message key of the message just sent,
though as this is an *ESCAPE msg, it will end your PGM at this point.
9 	Error code 	I/O 	Char(*)
Standard API error structure

Hello Robert,

Thanks. So the C style return value aren't honored.

> Note: The escape msg must be sent to the subsystem routing PGM, usually
QCMD. (see Img-2)  If you have a "non-standard" *SBSD with your own routing
PGM, then you will have to see how that considers a job to have aborted.

Thanks for the hint. The send pgm message API hat a lot of options, and I
have not yet achieved a comfortable level of understanding about messages.
But I'll try.

:wq! PoC
