Preface
Printing History
New editions are complete revisions of the manual. Update packages,
which are issued between editions, contain additional and replacement
pages to be merged into the manual by the customer. The dates on the
title page change only when a new edition or a new update is published.
No information is incorporated into a reprinting unless it appears as a
prior update; the edition does not change when an update is incorporated.
The software code printed alongside the date indicates the version level
of the software product at the time the manual or update was issued.
Many product updates and fixes do not require manual changes and,
conversely, manual corrections may be done without accompanying product
changes. Therefore, do not expect a one to one correspondence between
product updates and manual updates.

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
HP Pascal/iX Reference Manual
provides material about HP Pascal and
its system programming extensions. It is intended for experienced Pascal
programmers.
