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.

Message

When the effect of the update command has been cancelled, the message L n is displayed, where n is the number of the line on which the update was undone.
