Re: bye with exit status

iForth:
T: BYE  ( -- ) 0 TERMINATE T; ANS
TERMINATE                                              IFORTH
     ( n -- )
     Disconnect the server from the processor. Remove the server
     program on the host computer and let the server return the
     implementation defined error code n to the operating system.
     See also: BYE
 : TERMINATE
     ??CR [ =FILES ] [IF] FLUSH BLOCK-FID @ ?DUP
                          IF CLOSE-FILE DROP 0 BLOCK-FID ! THEN
                   [THEN]
     BYE! T;  ( error-level -- )
BYE!                                                 IFORTH
     ( -- )
     Send the 'disconnect server' command over the boot link to the
     server (if there is one). The server disconnects upon receiving
     this message and exits itself. All knowledge about open files
     is lost. If there is no server this command is the same as BYE .

Same as remarked by minforth: there is a exit-handler chain in
which the user can plug arbitrary routines.
The chained handlers were very popular with Hanno Schwalm because
he loved generating executables. I don't use them myself because
iForth is the default shell for my main activities.
