So it sounds like the CRC has no meaning.  If your system is
re-computing the CRC, then the segment could be invalid because of
in-transit corruption (or any other reason).  If I'm wrong about that,  
please explain more about it.

This sounds like RCs not doing their job properly.  Why are they not 
being held accountable to do it correctly?

 WD> If a segment arrives without CRC, idem ditto.

So this is the crux of my (original) question.  If it arrives without a 
CRC, then one can assume that MakeNL was not used to produce the 
segment.  To repeat my original question, is MakeNL really needed?  A 
segment is just a text file that gets "processed" by MakeNL, and it 
sounds like all that MakeNL is actually doing is calculating a CRC.  Is 
that serving any valid purpose, especially now that we know the validity 
of the CRC is ignored anyway?

In other words, can't the *C's just edit their segments with their text 
editor of choice, and then get it to the upstream *C via whatever method 
they like (netmail or email)?  What role does MakeNL perform in this 
process that actually matters?

Thanks for any info you can provide!
