That's interesting; I thought I recognized the format. I wonder where in the world I
could be remembering it from? It is surely not parsed by either COMND% or GTJFN% and I
don't believe Tops-20 NFT currently allows it. However, I haven't really gotten
into tinkering with NFT, yet. I'm finishing up some changes to FAL and DAP and then
I'm probably going to work with Johnny a bit to iron out some oddities in the email
interface (SMTP DECnet and Tops-20 MAIL11).
I keep thinking about implementing rename in Tops-20 DAP, but I just stumbled over what
appears to be a BLISS based implementation of FAL and DAP which MRC never seems to have
put up. Maybe it's great.
So what era does Ultrix 2.2 hail from? I believe we had an early version, something like
1986 or 1987. However, I doubt they put that syntax in and then took it out. So do I
understand that DECnet wouldn't have been available on Ultrix 1.x? I can't
remember what version we had, which is remarkable because I wrote the entire Id system for
it (using Ingress).
DECnet-Ultrix 2.2 is from 1988. There was a version of DECnet for Ultrix 1.x, I
think it was 1.2, but it did not have LAT support included. At the end of the
DECnet-Ultrix 1.0 project I had a couple of weeks waiting for the next project to get spun
up so I implemented LAT host support. Then I found out that the LAT implementation had
been promised to the O/S group and, in particular, someone I had been working closely
with! I don?t think they ever shipped my implementation.
We appreciated some aspects of Ultrix; as I recall, it
had both System V and BSD functionality. I used the System V semaphore interface to
implement locking for the Id system. That much I remember; wrapping the calls in routines
called P(); and V(); (obviously). Regretfully, this is the only Dutch I ever learned...
I thought Ultrix had DECnet and LAT at a very early date; at least I remember the sales
droids trying to talk that up. However, if it didn't have it, then that wouldn't
surprise me. The effect of the cancellation of the 36 bit line was nothing short of
electrifying. I think my favorite quote was Ralph Gorin, upon being promised something
which paraphrased, went something like this, "You're asking us to jump out the
window under the assurance that you will have a net ready before we hit the floor."
