This may be the second time folks have seen this question sort of:
how do you reference dua0, dua1, dub0, dub1 during the different phases
of an install?
I see refs to ra0*, ra(0,1,0), ra(1,0), ra(0,0,1), or am i missing somethings??

Do the install functions (copy, edlabel) assume that if you leave out
a field that it defaults to 0?
as in ra(1,0) - does this indicate dua1 or dub0?
thanks in advance
