Error Stack (-errorstack)

Use Error Stack (-errorstack) to allow error objects to save the ABL call stack in the CallStack property of an error object at the time the AVM generates the error object.

When -errorstack is specified, the ERROR-STACK-TRACE attribute of the SESSION handle is set to TRUE. The default value for this attribute is FALSE. While saving the call stack is a useful debugging feature, it can also consume resources and can potentially affect performance. Enabling ERROR-STACK-TRACE with this startup parameter is not recommended in a production environment.
