1	REDO_$

		The Redo Command enables users to capture the previously 
	typed DCL command for editing.  This feature is especially useful
	when typos are made in long command strings.  The user need only
	correct the typos rather than retype the whole command string.
 	The user must first enable the Redo Command Line Interpreter by 
	typing $REDOCLI to allow the use of the Redo command.  
	This command line interpreter is virtually transparent to the 
	user and captures the previous DCL command for Redo to act upon. 
	To disable the Redo Command Line Interpreter, type \\ .
	The following scenario shows the use of the Redo command after the
	Redo Command Line Interpreter has been enabled.

   $TYPE SYS$SYSDEVICE:[SAVERINO.SOURCE[*"MIKE.FOR 
					\_ !Erroneous DCL Command
   $REDO
   Command: TYPE SYS$SYSDEVICE:[SAVERINO.SOURCE[*"MIKE.FOR !Command Echoed
   Edit? [*"|] !To modify the line, type the old substring and the new 
	       !substring seperated by a "|". Type nothing after the "|" 
	       !if you only want to delete the old substring.
	       !Type <ret> after the Edit? to make no changes to the line
	       !and execute it.
   Command: TYPE SYS$SYSDEVICE:[SAVERINO.SOURCE]MIKE.FOR  
					 \_ !Corrected Command Echoed
   Edit? <ret>  !Prompt for further edits. Hit return since line is correct.
                !The corrected command is now executed.


   	CONSIDERATIONS WHEN USING THE REDO CLI:

		1.  Do not use the Redo CLI in batch streams.
		2.  Do not use Spawn from within the Redo CLI. However
		    the Redo CLI can be used once a Spawned subprocess
		    is attached to your terminal.
		3.  Do not use the Redo CLI on top of other user written CLI's
		4.  Some Vax utilities will not prompt for input from
                    within the Redo CLI.
