VAX FMS Form Driver Reference Manual

This manual describes the VAX FMS Form Driver, the run-time component of the Forms Management System (FMS) for the VAX/VMS operating system. It provides language-independent information essential for programmers to design forms and develop applications that use FMS for gathering and displaying data. The document covers the Form Driver's interaction with form descriptions, user action routines (UARs), terminal operators, key functions, call status, and asynchronous system traps (ASTs). It also offers programming techniques, examples, guidance on linking applications, setting up terminals, and a comprehensive alphabetical listing of all Form Driver calls with their arguments, descriptions, and status codes. This manual is intended for programmers familiar with a programming language, the VAX/VMS system, and FMS form characteristics.
