The mapping support package enables the user to format and control data streams routed between a terminal and an application program, and between two application programs. As a formatter vehicle, this package presents to the user program data streams devoid of device dependent code. This formatting capability is attained by user defined and package generated formats, or maps, which characterize input and output for CRTs and output for printer devices. The mapping support package additionally provides paging and scrolling multiple screen management control functions for CRT type devices.
