program (Spec. at 1, lines 4-7 and p. 7, lines 16-20). When a
"Major Error" occurs, "the program loses control of the
operations and is no longer able to detect itself the error or
failure" (Spec. at 6, lines 24-25).
Appellants' invention can be summarized as follows. The
program code is divided into logical subsets called Tasks
(Spec. at 13, lines 6-8). Each Task or subset is used to
develop a corresponding data table including a plurality of
Families each containing a description of the data fields to
capture in the event of the corresponding error (Spec. at 13,
lines 20-25). In a steady state, the Families are activated
one after the other at the key points of the program code such
that at each key point a Family is selected by the Task in the
Activation Table (Spec. at 18, lines 5-10). When a Major
Error occurs, the task loses control of the operations and the
error is instead detected by a control program, which calls on
an error handler program to retrieve the data fields
identified in the last subset (of the data table) that was
selected by the activation table (Spec. at 18, lines 18-21).
