shell


     Suspends JNOS and executes a sub-shell  ("command  processor"
under  MS-DOS).  When the sub-shell exits, Nos resumes (under MS-DOS,
enter the exit command).


     Note: see the COMSPEC environment variable.


     Background activity (FTP servers, etc.) is also suspended while
the subshell executes.  Note that this will fail unless there is
sufficient unused memory for the subshell and whatever command the
user tries to run.  When shelled out, Mailbox Operator connects and
ttylink incoming connections are refused.  A 'system unattended'
message is sent to the "connector" of that socket.
