I took a look at the Distributed Systems Annex and it didn't seem to do what I wanted to do. From as best I could figure (not really being a distributed computing kind of guy - at least not in the sense most people would mean) this looked like it was spelling out ways of sharing memory between two processes and of supporting "dynamic link libraries" (or whatever the term would be for the given OS) which might reside on a separate processor. I suppose this would be fine if all I wanted was to distribute the workload of one program across several machines. My problem is that I really have two separate programs which both run independently and the one program needs to interrogate the other program periodically concerning its state. (One of the programs simulates the embedded computer application on a workstation or PC - the other is a monitor program that would normally run on the workstation and interrogate the embedded computer.) As far as support for the annex, I vaguely recall somebody making mention of it being available in GNAT, but I certainly couldn't attest to that personally. I'm sure Robert Dewar could fill us in on this one. MDC Marin D.
