Type DECISION

The operators for writing EVSEQ are:

• + - choice, only one can be selected;
• * - repetition, the dialogue can be repeated.

The GI Menu shown in GI 1 is an example of a DECISION GI. This GI defines a dialogue in which the user must choose one of five alternatives, when he/she chooses End the dialogue ends.

In this case we have the declaration of a subGI called End. The GI End is the empty GI and it does nothing, it is used by Menu to end the dialogue.
