Description
An Exception object is automatically generated by dBASE Plus whenever an error occurs. The object’s properties contain information about the error.
You can also create an Exception object manually, which you can fill with information and THROW to manage execution or to jump out of deeply nested statements.
You may subclass the Exception class to create your own custom exception objects. A TRY block may be followed by multiple CATCH blocks, each one looking for a different exception class.
