This manual is written to serve a wide range of users of the
MPE/iX documentation set, from the occasional MPE/iX user, to the
experienced system manager.
NOTE: 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 information in this manual is presented as follows:
Chapter 1 of this book contains a glossary of terms defining many
Hewlett-Packard specific and industry-wide terms. In some cases,
there may be references to terms associated with a previous
Hewlett-Packard operating system, MPE V. Those terms are only useful
to MPE V users who have migrated to MPE/iX.
Many acronyms and abbreviations are used in discussing computer
products and processes. Chapter 2 of this book provides a list of
acronyms and abbreviations and identifies the meaning for each (the
complete definition of each is provided in the Glossary of Terms,
chapter 1).
