MSG-SPIN-DOWN (value 16417)

This event occurs when the user clicks the down arrow of an entry field with the SPINNER style. The program responds to MSG-SPIN-DOWN by decrementing the entry field by a specific value, not necessarily 1. Similar to the MSG-SPIN-UP event, if the entry field has the AUTO-SPIN style, you can set the EVENT-ACTION to EVENT-ACTION-FAIL to prevent the control from decrementing the value itself.
