Hi,
I am trying to write a ABEND program for my system.
(i.e. a program which can be used to forcefully abend)
Can anyone provide me with a sample code ... or least how to go about it? |

IBM has modules that you can CALL to force an ABEND. But, why?
The program that forces the ABEND (your new pgm) is the primary program in the dump. What use is that?
If you can code all your application programs to CALL your new ABEND program, you can code all your application programs to display or dump relevant data to aid in debugging, and exit with a return code > zero that can be recognized by a scheduler.
In other words, to come down in an orderly fashion.
To force the ops-sys to go thru an ABEND process is unnecessary, wasteful, thoughtless, pointless, costly and just dumb. It takes a ton of cycles for the ops-sys to handle and ABEND.
but, if you just gotta. The tried and proven method is to preload a comp-3 field (either by redef or a Reference Modification move) with spaces and add 1. |

If your shop does not already have a standard routine to call for that purpose, you could set a high return code and let your schedular catch the error and flush the rest of the job.
Alternately, a dynamic call to a non-existent module will work too..... |

Also for my information .. can you please let me know what are the IBM modules that can be called to force a abend? |

Indeed, there is an LE Callable service, called CEE3ABD.

GA22-7560-03 Lang Env Debugging Guide and a quote from the the Application Programming on z/OS Guide (attachment):
| Quote: |
errors and handling bad input. Your application should be designed to:- Validate input before using it
- Issue detailed error messages to simplify debugging
- Consider adding diagnostic tracing to the application which can be turned on and off
- Where possible, terminate a single transaction without taking down the entire server
|
Even if your environment is OS390, LE exists. Go to the IBM Library Server Library and search for SA22-756 Books, pick the ones for your OS. There are routines for dumps, (the debugging guide, above, explains how to read a dump), and task termination requests that return a user-requested return code for the system. |

Hello,
To force a user abend, you might try:
| Code: |
77 COMP-CODE PIC S9999 COMP.
.
.
.
MOVE uuuu TO COMP-CODE.
CALL "ILBOABN0" USING COMP-CODE. |

Sure!
I am dynamically calling a non existing module to serve my purpose. |
