Abstract
Abstract A paging receiver has a predetermined number of displayable characters, a microcomputer for receiving and processing data messages, a plurality of control switches for operating the computing means, and a memory for storing a plurality of received data messages. The microcomputer selects a data message to display from the memory, arranges the data message into a plurality of screens, computes an individual variable screen timeout value for each screen, and displays each screen on the display in a predetermined order for the screen timeout value computed. The screen timeout value computed on the basis of the message content of the screen, the presence of control characters in the data message, or the generation of input signals from the control switches. The screens can be displayed in a forward direction or a reverse direction. Each direction can either be a fast or a slow rate.
