Application Level Mapping (UNIX and VMS)
An application created with 4GL or one of the embedded query languages can use its own set of mappings, invoked by the set_frs frs or set_forms frs (for 4GL) statements. Applications developers can use these statements in an application to read in a key‑mapping file that is specific to that application or to map an FRS key to a function, control, or arrow key explicitly in the application code.
Application‑level mappings take precedence over all other mappings. For more information on application key mapping, see the Forms-based Application Development Tools User Guide.
