摘要： A controller capable of interacting with a remotely located computer has an object-oriented control structure facilitating remote access to data formatted in accordance with instructions defined by the controller. The control structure may be organized around a database of object items each associated with a control function. For each control function, the items include one or more procedures for performing an action associated with the control function, and one or more procedures for displaying data associated with the control function. The action procedures effectively define the controller's repertoire with respect to a particular control function. The display procedures comprise instructions retrievable and executable by the remotely located computer, causing display thereon of the data in a predetermined format (i.e., the format prescribed by the instructions). The controller facilitates selection and performance of actions in the database, and execution of the display procedure makes the display instructions accessible to the remotely located computer.
