An entry field is a control window that enables users to enter text. A command entry field is used for typing commands, and may be programmed to accept entries recognized by the application.

For example, a command entry field might be used in an interpreter with a Presentation Manager interface. The field would accept a request from the user and execute it. Similarly, a command entry field might be used in an editor in a "command mode" to accept advanced instructions not associated with any editing keys. Any time the user has a limited number of correct responses, a command entry field may be appropriate.

Help windows for application commands can be associated with a command entry field by imbedding the index command tag (:icmd.) with a command name in the window that describes the command.

When the cursor is positioned in the associated entry field and the user presses F1 or selects the Help push button, titles of windows that contain these tags are displayed in alphabetic order in a list box window.
