DPCX was an operating system

hoped it would help their installed base of IBM 3790
customers migrate to the 8100 and the DPPX
operating system. It was mainly deployed to support a word processing system, Distributed Office Support Facility (DOSF) which was derived from the earlier IBM 3730
word processing system.
Like DPPX, it was written in the 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 IBM Distributed Office Support System(DISOSS) running on data host. 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, Displaywriter, and 5520 Office System.

In the late 1970s, the IBM 3730, a word-processing variant of the IBM 3790 was announced. It used 3790 hardware but its software made it a dedicated shared-logic word-processing system which could support a dozen or more word-processing IBM 3732 terminals....

System/370
The IBM System/370 was a model range of IBM mainframes announced on June 30, 1970 as the successors to the System/360 family. The series maintained backward compatibility with the S/360, allowing an easy migration path for customers; this, plus improved performance, were the dominant themes of the...
