                (GUI input mode)

    Activate  a  choice widget which will return a value among the specified
    list. The widget will be created by command GUI\GO. This option is  usu-
    ally  combined  with a /PROMPT option. If the last specified value is an
    asterisk, the choice widget will be  editable  and  any  value  will  be
    valid.

    The choice list can also be given as a character array variable.

    If the /CHOICE has no argument, the Variable will be displayed, but can-
    not be modified. This mode can be useful to display  control  parameters
    in  a  menu,  or variables which result from operations with other vari-
    ables.
