---------------------------------------------------------------------------------------

Decision Table Name   Press Return          This field defaults to the name used in the

Questions                                   The remainder of this screen contains eight
                                            sets of three fields.  The fields are IF 
                                            Data name 1, IF Test, and Data name 2.
                                            Each set of three fields specifies a
                                            question to be resolved.

Data name 1           V-mode                This is the name of the first data item
                                            that is to be tested.  The rules for the
                                            construction of an IF statement in a
                                            decision table are the same as those for
                                            the construction of an IF statement in a
                                            logic block.

IF Test               =                     This is the relationship that must exist
                                            between the two named fields.  (A decision
                                            table question can also test the status of
                                            a single item.  For example, the test can
                                            be *BLANK.)

Data name 2           C-add                 This is the name of the data item that the
                                            first data item is tested against.  In this
                                            case it is the alphanumeric constant add.
