APPC Subsystem on MPE/XL Node Manager's Guide (30294-90007)

Preface

This manual introduces the fundamental concepts and vocabulary of

Advanced Program-To-Program Communication. It also provides the

information necessary for conﬁguration and day-to-day operation of the

APPC subsystem on the MPE XL operating system.

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 HP 3000s (Series 900) in what is

known as compatibility mode.
