AT9-88-009 DYNAMICALLY EXTENDING SELECTION CHOICES Abstract An extended selection field is disclosed for use in selecting one or more choices from a list on an information system display. The extended selection field exhibits the behavior and appearance of a standard single choice field, with the additional capability to switch into a multiple choice mode to override the single choice restriction. A single choice is selected using the standard technique of moving the selection bar to the desired choice and pressing the Enter key. However, the single choice restriction may be overridden by using the standard multiple choice selection technique of moving the selection bar to a first desired choice and pressing (instead of the Enter key) a choice selection key such as the space bar. The field then exhibits the behav- ior and appearance of a standard multiple choice field. The single choice selection bar immediately changes to a multiple choice indicator and the opera- tor receives immediate visual feedback that the system is enabled to accept multiple choices. At the conclu- sion of the multiple choices, the Enter key is de- pressed to submit all of the selected choices for processing. The single choice mode can be reestab- lished by deselecting all of the selected choices.
