Error object
The Error object is used to record execution-time errors.
You can access the Error object from a script (typically in the
SystemError event) to learn which error occurred and where it occurred.
You can also customize your own version of the Error object by defining
a class user object inherited from the built-in Error object.
For more information about creating a custom
Error object, see the chapter on user objects in the PowerBuilder
Users Guide. For information on using try–catch
blocks to catch runtime and user-defined exceptions, see Application Techniques and
the PowerScript Reference.
