Preface

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 under 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 Quick Reference Guide offers a synopsis of the MPE/iX operating system and its major subsystems. Each chapter corresponds to a manual in the MPE/iX set. The table below lists the chapters in order and the corresponding MPE/iX manuals.

Commands, intrinsics, and utility descriptions are in alphabetical order within the chapters. Each of the chapters shows syntax for commands and functions. Some chapters include examples; user input is underlined.
