The eleventh edition of the MPE/iX Commands Reference Manual is one volume with command descriptions alphabetically from A through X. This manual is written for all users of the HP 3000 MPE/iX Computers. MPE/iX, Multiprogramming Executive with Integrated POSIX, is the latest in a series of forward-compatible operating systems for the HP 3000 line of computers.

In HP documentation and in talking with HP 3000 users, you will encounter references to MPE XL, the direct predecessor of MPE/iX. MPE/iX is a superset of MPE XL. All programs written for MPE XL will run without change unde MPE/iX. You can continue to use MPE XL system documentation, although it may not refer to features added to the operating system to support POSIX (for example, hierarchical directories).

Finally, you may encounter references to MPE V, which is the operating system for HP 3000s, not based on the PA-RISC architecture. MPE V software can be run on the PA-RISC (Series 900) HP 3000s in what is known as compatibility mode.

The MPE/iX Commands Reference Manual is organized into eight chapters. A description of each chapter follows:

Chapters 2 thru 8 of this manual, explains the purpose, syntax, parameters, and operation (including examples) for each MPE/iX command. If you know which command to use for the task you wish to perform, turn directly to that command definition. For your convenience, commands are organized alphabetically. If you don't know which command to use, Chapter 1, which contains a listing of commands by task, is a good place to start. After reading the brief description, turn to the appropriate command definition.
