Summary 

In this lesson you defined a decision table.  A decision table is similar
to a set of IF-THEN-ELSE statements.  You can use a decision table to
test a number of conditions and then execute a specified set of actions
in a specified sequence depending on the results of the test.

Decision tables have the following features:

   *   To define a decision table, you must complete four screens.  These
       are the decision table header screen, the decision table questions
       screen, the decision table actions screen, and the decision table
       relationships screen.

   *   The questions for a decision table are in the same format as logic
       IF statements.

   *   A decision table can execute any action that can be called from a
       menu.  These include functions, processes, screens, and further
       decision tables.

   *   For any given set of outcomes for the decision table questions,
       the decision table relationships specify which actions are
       executed, and the sequence in which they are executed.

   *   A decision table must be generated before it can be used in the
       application.
