NOTES: VERSION 2.03

-Fexec now works for BCPL programs (see note below on RUN)
-New _path variable (ala suggestion from Steve Drew).  See instructions

Note on RUN.  Do not redirect output or input for the RUN command.  It
does *really* strange things.  To redirect output from a command being
RUN, redirect that command as follows:

% run ">xx" charlie

That is, you are passing the string ">xx" to the the RUN as well; the
redirection will be handled by run's cli.
