[ Type code = F ] Exits as soon as the maximum (xmax) number of characters entered, or an enabled exit code is used; no Return or Enter needed. See code <. To alert the operator, INFLD will make the cursor blink while editing fast fields.

F generally has the same effect in a GUI field as in a text input field—i.e., causing the field to exit automatically when the maximum number of characters are entered. There are some special GUI situations, however, where it takes on additional meaning. One occurs with drop-down controls (combo boxes or date pickers), where it causes a single-click on an entry in the drop-down list to cause the item to be selected the field to exit. Otherwise, single-click in this case would normally just close up the drop-down list and return to the edit field.
