TPF Mapping Support

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.

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.

The CONFIG macro parameter MAPSP is used to determine whether or not mapping support is included in the system. See TPF Data Communications Services Reference for complete details.
