The interpretation of an address depends on the context it is used in.
If a subprocess is being debugged then addresses are interpreted
in the usual way in the address space of the subprocess.

In C, the `true name' of an external symbol begins with
.Li \_ .
It may be necessary to utter this name to distinguish it
from internal or hidden variables of a program.
