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. 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 .
