Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Distributed Processing Programming Executive was an operating system introduced by IBM, pre-installed on selected computer models in the 1980s. DPPX was written in Programming Language for Distributed Systems, a PL/I-derived systems programming language, similar to the PL/S systems programming language used for MVS and VM. Part of the DPPX/370 development process was developing a PL/DS 2 language, which was based on PL/DS, but with changes necessitated by the changed instruction set. The user interfaces of DPPX were very clean and easy to use, the syntax of the commands, the whole concept and ideas of DPPX looked very straightforward and consistent, and each and every aspect was documented online and in a rich set of well organized printed manuals.
