The system variable the_env is currently not used by the OS, but is
reserved for use by Atari.  It is documented as a "null environment;
four bytes of 0."  Back in the dark ages of TOS, before the environment
started getting set up later on in system startup, these four bytes
were a convenient place for GEMDOS to pick up a null environment
string.  It's done differently these days, but the cruft of the_env is
still lying about.

If you're looking for low memory space to put something, there are much
better places than at the_env.  Please don't use it.

I don't know of any software that uses it currently.  I am still
planning (someday) on releasing the DA/program environment-setter that
I have put together, and as system software, I may have it use the_env
for something meaningful.  If I do, I'll be sure to document its
purpose far and wide.
