 | 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. |
