Undo - cancels the last command that changed the item.
Syntax
X
Limitations
This command is useful if only the most recently entered command in an editing session is erroneous.
This command must be used before an F (Flip) or FS (File Save) command is issued.
X Following Multiple Line Replacement
When X is executed once immediately after a multiline replace (R command), just the last line changed is restored to its state before the R command was executed. If X is executed a second time, all of the lines changed by the R command are restored to their states before it was executed.
Note
To cancel all changes since the last F or FS command, use the XF command.
Message

the message L
n
is displayed, where n
is the number of the line on which the update was undone.
