There are several new reserved words in BASIC Release 2.0 that are not
documented: ENVIRON, ENVIRON$, ERDEV, ERDEV$, INTER$, IOCTL, IOCTL$,
KEY$, and SHELL.
 
 
ENVIRON "X=value"       command - sets environment variable X;
                        like DOS  SET X=value
 
ENVIRON$("X")           function - returns value of environment
                        variable X.
 
ERDEV, ERDEV$           ?
 
INTER$                  ?
 
IOCTL, IOCTL$           access to the IOCTL functions in DOS (?)
                        see DOS pages 14-7 and D-39
 
KEY$                    ?
 
SHELL                   command - takes you to DOS command
                        level;  return to BASIC with EXIT.
 
SHELL "command"         command - execute the specified DOS command
                        and return immediately.
