Learning HP EDIT

Chapter 5  Undoing Mistakes 

HP EDIT lets you recover from editing mistakes by letting you undo any
command you have executed since you read in or last saved your file.

To practice the Undo feature, use the file created in the last lesson.
If you exited HP EDIT since doing the last lesson, text in the file
LESSON4.  If you have not exited, simply return to the Main Keys function
key set.
