This manual serves two purposes: It is a training manual for programmers who wish to create LU 6.2 API applications, and it also serves as a reference manual.

NOTE: The information in this manual can be used to create LU 6.2 API applications on MPE V systems or MPE XL systems. Any differences between LU 6.2 API on MPE V and LU 6.2 API on MPE XL are noted in the manual.

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.
