MPE/iX User Interface MPE/iX has a user interface that includes a command language, on-line HELP facility, user-defined commands (UDCs), and command files. The MPE/iX command language is processed by the Command Interpreter. It contains all necessary commands to direct and control the system. You can enter identical MPE/iX commands during a session or through a job; MPE/iX has no separate control language for jobs. You can also issue MPE/iX commands in a command file. Actions MPE/iX commands can perform include: * Initiate and terminate jobs and sessions. * Run system programs and utilities. * Compile, link, load, run, and debug programs. * Create, maintain, and delete files. * Display file information. * Display job, session, or device status. * Transmit messages. * Establish communication with local and remote computers. * Control and manage system resources. If the command interpreter (CI) detects an error in command syntax in interactive mode (during a session), it provides a descriptive error message specifying the erroneous parameter and prompts you to correctly reenter the command. If it detects a syntax error while running, it lists the error on the output device and halts the job. You can use the command language to create batch files (also called stream jobs) that contain control statements and variables. Execution of the commands in the file can be altered at execution time by using these control statements.
