[HECnet] Use of Area 63 for Testing

[Peter Lothberg]

So for the academic networks in the past when DECnet was supported on a 
world-wide basis, called "HEPnet" and run by the high_energy_physics 
people and DOE we used the max-area and PMR. There where PMR objects on 
VMS to.

So all of the DECnet nodes in the Nordics where in areas higher than
(if I remember right) 42. 

So 43-63 was used locally, and the global nodes where in lower area 
numbers and if you wanted to talk from something in "the big world"
you used the PMR object of a node in the "low region" 

For example, the VAX at Fysicum in Uppsala was such a node in area 22..
