DC Programming Techniques › Controlling Abend Processing

Controlling Abend Processing

A program can abnormally terminate in the following ways:

• DC terminates a program upon encountering a processing error (for example, a program check).
• The program terminates itself upon discovering a situation that would result in invalid results.

DC allows you to specify abend exits, which are invoked upon a system or a user abend request. These exits specify a program to be invoked in the event of an abend; you can include an abend exit program for each level of a task. Abend exits allow you to determine the cause and severity of the abend. Based on that information, you can return control to the task, return control to the next-higher abend exit, or terminate the program.
