This article describes a method for implementing a protocol to facilitate and manage direct object manipulation between independently developed programs displayed on a computer terminal display. Direct object manipulation is the capability to select an object on the display screen and dynamically drag that object to another area on the screen and leave the object in the new location on the screen. There are two primary forms of actions implied with direct object manipulation; the first is a direct repositioning of the object to another location on the screen. The second is an action-object type of direct object manipulation where the object undergoing direct object manipulation is dragged over another object, the target object, initiating an action.
