Detailed Description

The <class>Exception.SystemException</class> class provides access to information about the most recent system error.

It is the type of object assigned to the CATCH variable when a system error occurs inside a TRY block. Only the System should create an instance of this class.

For system exceptions, the values of the properties should be interpreted as follows:

Name: The name of the exception, such as UNDEFINED.
Code: A numerical code that represents the exception, defined by the system.
Location: A string containing the routine and line where the exception occured.
Data: Depending upon the actual exception, extra data about the exception. For example, for an UNDEFINED error this would be the name of the variable that was undefined.
