ASSIGN [X[=]Y[...]]                    Routes disk I/O to another drive
ASSIGN + Reassigning the Default Drive
     Instructs DOS to use a disk drive other than the one 
originally specified by an application program.
    VERSION
          PC-DOS 2.0+
	  MS-DOS equivalent: ASSIGN (3.0+)
    TYPE
          External
    SYNTAX
	  [d:][path] ASSIGN d1 = d2
    OPTIONS
	  [d:][path]	 Before ASSIGN, specifies the drive
                         letter and path that contain the ASSIGN 
                         command.
	  d1		 Specifies the current drive letter to
                         which disk I/O requests are sent.
	  d2		 Specifies the drive letter to which disk
                         I/O requests are now to be sent.
     ASSIGN allows you to reassign the default drive before 
running a program that includes drive names in the files it 
accesses so that you can run drive-specific version 1 programs on 
a hard disk.
    EXAMPLES
	  ASSIGN A = B
assigns drive A to drive B so that whenever drive A is requested, 
drive B is used.
	  ASSIGN A = C B = C
assigns both drive A and drive B to drive C.
	  ASSIGN
reassigns the default settings so that requests for drive C go to 
that drive.
    UNDO
     Issue the ASSIGN command as
	  ASSIGN
with no parameters to return drives to their normal assignments.
    NOTE
     Be careful to reassign drives to their normal assignments 
before running another program that contains drive designations. 
If you reassign the designation of the drive that contains the 
ASSIGN program, you cannot clear the assignment without 
rebooting. Do not use ASSIGN with the BACKUP, RESTORE, LABEL, 
JOIN, SUBST, or PRINT command. In addition, FORMAT, DISKCOPY, and 
DISKCOMP ignore drive reassignments.
