I finally put something together that is analogous to the RSX NFT /ID switch. Basically,

Gee, MIM:: does a lot of stuff, so I regrettably remain with a pretty bad case of data
envy... And I really have to get off my butt and implement rename.
Is there an ASCII version of DAP 7.1 anywhere on HECnet that I could download? I was
curious about file preallocation whose bit is defined in the 5.6 document, but not really
explained, as far as I saw.
I have never seen one, which is odd because obviously both 6.0 and 7.0 were implemented
and therefore must have existed. There are various other DECnet Phase IV era specs that
appear to be lost, for example the IV-plus routing spec. I implemented bits of that in
PyDECnet from memory (hopefully correctly...) but there are other things, like congestion
control and equal cost path splitting, that I sure would like to see specified.
There is a VMS 4.x listing set on Bitsavers (scanned microfiche) which I think includes
DAP 7.0 code. I spent a little time reading through pieces of that when I was working on
the DAP code in PyDECnet. So you might try that; chances are you know Bliss, which I do
not. And/or you can look at the PyDECnet code, though of course then you'd be dealing
with second generation reverse engineering.
