'''DPCX''' ('''Distributed Processing Control eXecutive''') was an [[operating system]] for the [[IBM 8100]] small computer system.<ref>{{Cite journal|last=Tanton|first=Theresa T.|date=30 Jul 1979|title=Choice involves many factors: IBM 8100 and 4300 aimed at different users|url=https://books.google.com/books?id=erK4_MHuqP8C&pg=RA1-PA32|journal=Computerworld|volume=13|issue=31|pages=Special Report/10}}</ref><ref>{{Cite journal|last=Henkel|first=Tom|date=3 Mar 1980|title=For distributed operation: missing links plaguing IBM's 8100 system|url=https://books.google.com/books?id=6xo2WButCyEC&pg=PA5|journal=Computerworld|volume=14|issue=9|pages=5}}</ref> [[IBM]] hoped it would help their installed base of [[IBM 3790]] customers migrate to the 8100 and the [[IBM DPPX|DPPX]] operating system.<ref>{{Cite journal|last=Waters|first=F. C.

Like DPPX, it was written in the [[IBM PL/S|PL/S]]-like PL/DS language.  The applications, including much of DOSF, however, were written an interpreted language that was "compiled" using the [[System/370]] assembler macro facility.

The 8100/DPCX/DOSF system was the first type of distributed system to connect to the [[Disoss|IBM Distributed Office Support System (DISOSS)]] running on data host.<ref>IBM Red Book DISOSS</ref>  Later versions of DISOSS relied on SNA Distribution System ([[SNADS]]) and eventually became [[peer-to-peer]] communication of documents which complied with [[Document Interchange Architecture]] (DIA) and [[Document Content Architecture]] (DCA) as other types of distributed system gained DISOSS support – [[Scanmaster]], [[IBM Displaywriter System|Displaywriter]], and [[IBM 5520|5520]] Office System.
