Issue/Introduction

Why does ADS not disable dialogs that abend with DC175020 APPLICATION ABORTED (data exception)?

Environment

Release: All supported releases.
Component: ADS.

Resolution

These abends are identified by ADS before an actual assembler program check occurs. The result is that the program check count does not increase for the dialog which is therefore never marked disabled and out of service.

There is a sample user exit 05 attached at the bottom of this article. It checks each task that terminates to see if it is ADS. If it is ADS it checks to see if it abended with DC175020 and increments the program check count. When the program check count exceeds the program check threshold, the dialog will be disabled.
