Message-ID: <1992Sep23.191127.27728@nosc.mil> (raw)
Several of the entries in this thread have raised the spectre of shared
memory. Without addressing whether shared memory is good or bad, let's clar-
ify that it's not the point of this thread. _Global_ is an issue of name
scope, of visibility. Ada gives perfectly adequate means for accessing
shared memory without requiring that the names of the data in the shared mem-
ory be global (the address clause). The shared memory is a shared resource,
of course, and must be handled carefully, but the problems of shared memory
are quite different from the problems of global data, at least in Ada.
