This example shows how to program the ON VALUE-REQUEST event on selection screens to allow the F4 key / search help button on a field, instead of letting the default system behavior (none, search help, value table, etc.) In this example, a popup dialog is displayed to show a list of values and it allows the user to select and return a value into the selection screen field.
