Editing HP Multi-Programming Executive (section)

== Description ==
It runs on the HP 3000 family of computers, which originally used HP custom [[16-bit]] [[stack architecture]] [[Complex instruction set computer|CISC]] [[Central processing unit|CPUs]] and were later migrated to [[PA-RISC]] where the operating system was called '''MPE XL'''.

In 1983, the original version of MPE was written in a language called SPL ([[System Programming Language]]). MPE XL was written primarily in [[Pascal (programming language)|Pascal]], with some [[assembly language]] and some of the old SPL code.

In 1992, the OS name was changed to '''MPE/iX''' to indicate [[Unix]] interoperability with the addition of [[POSIX]] compatibility. The discontinuance of the product line was announced in late 2001, with support from HP terminating at the end of 2010. A number of 3rd party companies still support both the hardware and software.

In 2002 HP released the last version  MPE/iX 7.5.<ref>[http://www.hpmuseum.net/exhibit.php?swc=22 3000-MPE (Software)], on HPMuseum site, retrieved on October 2019.</ref>
