Special Note
MPE/iX, Multiprogramming Executive with Integrated POSIX, is the
latest in a series of forward-compatible operating systems for the
HP e3000 line of computers.
In HP documentation and in talking with HP e3000 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 e3000s, not based on the PA-RISC architecture. MPE V
software can be run on the PA-RISC HP e3000s in what is known as
compatibility mode.
