-REDO 

Allows you to edit a command entry.

SYNTAX 

     -REDO [edit request]

PARAMETERS 

edit request     Any valid edit request string as described under
                 operation of the -REDO command.  The edit request is
                 applied to the last command that was entered and the
                 resultant command is then executed.  If an edit request
                 is entered as a parameter to the -REDO command, the user
                 is not prompted for any more changes.

OPERATION 

The -REDO command allows you to correct certain kinds of errors in an
incorrect command entry or to change a correct command entry.  The -REDO
command only applies to the last command entered.  When the -REDO command
is entered, Segmenter enters a mode similar to the Editor and displays
the command to be modified.

To modify the command output by SEGMENTER, position the cursor (using the
space bar on the terminal) under the character(s) to be modified, then
enter one of the following sub-commands:

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

I                Insert.  Inserts one or more characters immediately
                 preceding the character above the cursor.  The D and I
                 sub-commands can be used in conjunction to delete
                 characters, then insert new characters.

R                Replace.  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 sub-command.

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

EXAMPLE 

     -BUILDS MYSL,2000,1
     *** ERROR ***
     ILLEGAL COMMAND NAME
     REDO                            (Request to enter command string)
     BUILDS MYSL,2000,1              (SEGMENTER displays command)

         IL                          (Insert L)
     BUILDSL MYSL,2000,1             (Corrected command displayed)

Note that the letter S can be entered without the sub-command R, because
R is the default sub-command.  For example,

     -BUILDXL MYSL,2000,1
           S                         (Replace X with S)
     -BUILDSL MYSL,2000,1            (Corrected command displayed)
