However, I noticed some code in COMND% that checks to see that a node name has at least one alphabetic character in it. I had never thought about that and was wondering what the actual standard says (or where that standard is).
I forgot to answer that last question. The answer is: the Network Management spec. For example, the Phase IV spec (netman40.txt) says:
node-name A node name consists of one to six upper case
alphanumeric characters with at least one
alpha character. A node name must be unique
within a node and should be unique within the
network.
Interestingly enough, the Phase II spec (NSP) is less precise; it only says that nodenames are alphanumeric without explicitly requiring at least one letter.
