Adding and removing clear from drop-down lists

By default, when the Display Type property of a character field with a menu is set to Drop-Down List, the last item on the first-level menu in the drop-down list is (clear).

You do not manually add the (clear) item to the menu attached to the field. Instead, the item automatically appears at runtime on the drop-down lists of all types, character, file, search, SQL, and data dictionary, of character field menus.

When users select (clear), any previously entered value is removed from the field.

If the (clear) item does not appear on a drop-down list, add it as follows.
