DPCX (Distributed Processing Control eXecutive) was anoperating system for theIBM 8100 small computer system.[1][2]IBM hoped it would help their installed base ofIBM 3790 customers migrate to the 8100 and theDPPX operating system.[3] It was mainly deployed to support aword processing system,Distributed Office Support Facility (DOSF) which was derived from the earlierIBM 3730 word processing system.
Like DPPX, it was written in thePL/S-like PL/DS language. The applications, including much of DOSF, however, were written an interpreted language that was "compiled" using theSystem/370 assembler macro facility.
The 8100/DPCX/DOSF system was the first type of distributed system to connect to theIBM Distributed Office Support System (DISOSS) running on data host.[4] Later versions of DISOSS relied on SNA Distribution System (SNADS) and eventually becamepeer-to-peer communication of documents which complied withDocument Interchange Architecture (DIA) andDocument Content Architecture (DCA) as other types of distributed system gained DISOSS support –Scanmaster,Displaywriter, and5520 Office System.
