Example

If there is an unhandled condition of severity 2 or greater, the default assembler user exit in z/OS returns to the system with a return code. You can change the default assembler user exit so that it forces an abend for unhandled conditions of severity 2 or greater.

Examples of conditions that are severity 2 or greater include:

Program interrupts
System abends
Conditions detected by Language Environment; for example, a program load failure

The ABTERMENC(ABEND) runtime option is an alternative way to force an abend for unhandled conditions of severity 2 or greater.
