Actually, according to the documentation (pg 25), the ADDRESS command
does not attempt to resolve the value of the variable. However, in
parsing, the variable name has already been shifted to upper case.  The
original "address mg" didn't work because the port was named "mg" and
not "MG".  If you want to do what you did above, try

    editor = "mg"
    address value editor


I think I've been bitten by this a couple of times. Note that there does not
seem to be a way of using "ADDRESS VALUE" along with a command at the same
time, as the parser would have trouble figuring out where the expression
stops and where the command starts.         -- Darren
