I have before me the PC 7300 assembly manual, which says "There is no limit
on the length of an identifier", while the C manual says "Although there is
no limit on the length of a name, only initial characters are significant:
at least eight of a non-external name, and perhaps fewer for external names"
My 7300 is not accessible to me at the moment, so I can not try an imperical
test, but I would interpret this to mean that the 8 character limit is not
a result of the assembler, which is not limited to 8 characters of significance,
but a restriction imposed by the C compiler itself.
