REDO 

Allows a user to correct or modify the last IMAGE/SQL utility command.

Syntax 

REDO

Prerequisites 

None.

Description 

Use this command to display the last IMAGE/SQL utility command entered.
Use the associated subcommands to correct or change the displayed
command.  The REDO command applies only to the last command entered and
is available only in interactive mode.  It is ignored with a warning in
batch mode.

Subcommands 

D       deletes the character above the cursor.  If D is repeated, each
        character above each D is deleted.

I       inserts one or more characters immediately preceding the
        character above the cursor.  The D and I subcommands can be used
        in conjunction to delete characters and then insert new
        characters.

R       replaces the characters above the cursor with new characters.  If
        one character is entered, the character above the cursor is
        replaced; if two characters are entered, two characters (the
        character above the cursor and the character to the right) are
        replaced; and so forth for additional characters.  R is the
        default subcommand and is only required when the character to be
        replaced is a D, I, R, or U.

U       undoes the effect of the previous D, I, or R subcommand.
        Entering a U, carriage return, then another U cancels all
        previous subcommands for this REDO command and restores the line
        being corrected to its original form.

Once the command is corrected, enter a carriage return to issue the
command.

Example 

In the following example, the DISPLAY MAP command is corrected using the
R subcommand.
