EQA9931W Requested user interface not available. Processing will continue as if a QUIT DEBUG command had been entered.

Explanation
The requested user interface is not available so z/OS® Debugger will quit processing events and the application
will continue to run. (Note that any calls to restart z/OS Debugger are ignored.) This behavior was specified in
the EQAOPTS customization module via the EQAXOPT macro invocation option NODISPLAY,QUITDEBUG.

Programmer response
Make sure the user interface specified as a suboption in the TEST runtime option is correct and
available. However, if you do not want the processing of a QUIT DEBUG command when this situation is
detected then change the EQAXOPT macro invocation option to NODISPLAY,DEFAULT in your EQAOPTS
customization module.
