User Commands

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.
