A common screen driver is described which presents a series of prompts and messages to the user. This eliminates the need to develop separate screen drivers in each utility and thus reduces development time and code space. This screen interface incorporates many unique features, such as a ringed cursor motion among the prompts, optional use of input handlers for each of the prompts, initial message display, interspersed messages and prompts, regeneration of the screen, and optional message display when regenerating the screen. An example of a screen generated and controlled by the screen driver is shown in Fig. 1. When the screen driver receives control, the top line is displayed using the address contained in the control table shown in Fig. 2.
