     Invokes a second command processor.
    VERSION
          PC-DOS 2.0+
	  MS-DOS equivalent: COMMAND (2.0+)
    TYPE
          External 
    SYNTAX
	  COMMAND [d]:[path][C string][/E:xxxxx]
    OPTIONS
	  [d:][path]	 Specifies the drive letter and path that
                         is searched to locate the command 
                         processor you wish to start.
          /P             Causes a second command processor to 
                         become memory-resident; you must then 
                         restart DOS to return to the original 
                         command processor.
	  /C string	 Passes a string (any command that can be
                         entered at a DOS prompt) to a second 
                         command processor, executes the command, 
                         and then removes the second copy of the 
                         command processor.
	  /E:xxxxx	 Specifies the size of the environment as
                         a base 10 integer between 160 and 32768. 
                         This number is rounded up to the nearest 
                         paragraph boundary.
     COMMAND allows you to run one batch file from within another 
and then return to the original batch file.
    EXAMPLES
	  CCOMMAND
invokes a second copy of the command processor, and this new copy 
will inherit the environment known to the primary command 
processor. 
	  CCOMMAND /C TEST2
starts a second copy of the command processor and executes the 
batch file TEST2.BAT, then returns to the original batch file 
TEST1.BAT.
    MESSAGE
	  Current drive is no longer valid
COMMAND found that the current drive is no longer valid. You may 
have deleted a network drive. Change the current drive to a valid 
one.
    UNDO
     To return to the primary command processor, enter the 
special command
	  CEXIT
