REDO

Allows you to modify and/or execute the previous NRJE subsystem command. Use this like the MPE REDO command.

Syntax

RED[O]

Subcommands

D: Deletes the character above the D. If the D is repeated, each character above each D is deleted.
I: Inserts one or more characters ahead of the character above the I. The D and I subcommands can be used together to replace strings of unequal length.
R: Replaces the characters above the R with the characters that immediately follow it.
U: Cancels the preceding subcommand, unless it was a U, in which case the original NRJE command line is restored.
Any character but D, I, R, or U.: Replaces one-for-one the characters in the string with the characters you enter.

Description

The REDO command allows you to correct certain kinds of errors in an incorrect command entry or to change a correct command entry, eliminating the need for re-entering the command in its entirety. The REDO command applies only to the latest command entered. When a REDO command is entered, NRJE enters a mode similar to the Editor and displays the command to be modified.

To modify the command output by NRJE, use the space bar on the terminal to position the cursor under the characters to be modified, then enter one of the subcommands described above. If you space over too far, use the backspace key to reposition the cursor.

The REDO command operates exactly like its MPE counterpart.

Example

>SHEW MINE      An incorrect command was entered.
 
NO SUCH COMMAND. (CI=721)
 
>REDO 
 
SHEW MINE       The incorrect command is displayed.
 
  RO            Enter the R subcommand below the character "E"
                you are replacing, followed by the correct character "O".
 
                You could have omitted the R subcommand.
 
SHOW MINE       The correct command is displayed.
 
[RETURN]        Enter another carriage return to execute this command.
