          Choice Fields

          A choice field (field type Ch) contains several text items, one or more of which
          may be selected as the field value. The items may be presented to the user in
          either of two forms:

          • A scrollable list box
          • A combo box consisting of a drop-down list optionally accompanied by an edit-
               able text box in which the user can type a value other than the predefined
               choices

                                 TABLE 8.79 Field flags specific to choice fields
BIT POSITION      NAME                      MEANING

18                Combo                     If set, the field is a combo box; if clear, the field is a list box.

19                Edit                      If set, the combo box includes an editable text box as well as a drop-
                                            down list; if clear, it includes only a drop-down list. This flag is mean-
                                            ingful only if the Combo flag is set.
