REDO COMMAND
The REDO command allows you to correct errors or to modify a command
previously issued. It applies to the last command you entered whether it
was syntactically incorrect or successfully executed.
In order to perform modification, move the cursor to the character which
you wish to modify by repeatedly entering the space character. This
position will be referred to as the 'edit position.' You can perform a
variety of operations at the edit position; you may insert, delete, or
replace the characters at the edit position. The following subcommands
are processed in the REDO mode:
A Appends characters at the end of the current line. If
the text is too long to accommodate additional
characters, a warning message is issued and no append
occurs.
B Breaks the line into two lines at the edit position.
After the break, the second line becomes the current
line. The edit position is placed at the first
character of the second line. This subcommand is used
when a line needs to be inserted.
E Exits the redo mode. All the edits you have made within
the REDO are annulled, and the command is not executed.
L Lists the edited command. The current line will be
marked by an asterisk after the line number.
X Stops the redo mode and executes the edited command.
+[n] Moves n lines forward. '+' moves forward by one line.
-[n] Moves n lines backward. '-' moves backward by one line.
D Deletes the character at the edit position. If you wish
to delete more than one character, either repeat the
D's, or mark the string you want to delete with the
beginning D and ending D with spaces embedded. If you
delete all the characters in the line, the line itself
is deleted.
I Inserts the characters following it at the edit
position. This is the only subcommand that can be
issued following the D subcommand.
R Replaces the characters at the edit position with the
characters following the R.
H Brings up the help messages for the REDO command.
If one of the command characters is not entered, any other character
entered will simply replace the character above it, as the default
editing mode is the "replace" mode.
