Does anyone recall any details about "EXCHANGE" -- software originally developed by UCLA for OS/360 MVT, and later ported to MVS.
This allowed message passing between regions or address spaces, using a concept where one job would put a message up on a "shelf" (in CSE in MVS), and the target job could periodically check that (named) "shelf" for any messages. It was loosely based on the idea of EXCP, with an EXCH macro for assembler users, and also had a PL/1 CALL level interface (what today we call an "API".) I can barely find any mention of "The EXCHANGE" from ULCA on the interweb. Does anyone recall if this software was ever made available on any of the SHARE tapes, e.g. for the OS/360 MVT or MVS projects, etc.? Or elsewhere? Thanks in advance. All the best, Mark S.
