Oh, the compiler I use has lots of that stuff, but it is printed in blue
ink (non-standard) and this seems such a basic concept (for a language
that provides Address clauses at all) that I was hoping for a standard
method.

Since one is looking at machine addresses, the code is by definition
non-portable, but recent experience in another language has made me
hyper-sensitive to vendor-specific enhancements.  If someday there were
a second compiler vendor for the platform, standard syntax might be
useful.
