Chapter 16 Multi-User File Handling This COBOL system provides the ability for independent Micro Focus COBOL programs to share data files in multi-user microcomputer environments. Each program running in a shared file configuration can have access to common data files, with file security maintained in a predictable and controllable manner. You specify file sharing with COBOL syntax in your program, rather than with program calls or any other means. The Language Reference contains details of this syntax, and there is further information on COBOL syntax for the various types of file organization later in this chapter. If you are running COBOL within a single-user environment, this multi-user syntax is accepted by the compiler, although it has no effect when you run your programs. This allows you to develop applications designed for use within multi-user environments in a single-user environment.
