Undoing Commands HP EDIT provides several undo commands that enable you to cancel previously executed commands. This ability is beneficial when you mistakenly issue the wrong command or issue a command that produces undesirable results. HP EDIT maintains a history of text modification commands, and can undo a single command or every text-altering command issued since you texted in the current file. When you have undone all text changes since last saving the file, HP EDIT displays a message indicating that there are no more changes since the last time the file was kept. However, you can continue undoing commands until you have sequenced through every modification since you texted in the file. HP EDIT limits the number of commands that you can undo. The command history is based on the information recorded in the back-up recovery file [REV DEL]. The recovery file contains one record for every original line in the input file, plus records for every text-altering command and line changed during the editing session. If your text-altering commands affect more text than the recovery file can accommodate, HP EDIT displays an error message. Refer to Undo Last Command, Undo Sequentially, and Undo All in chapter 4 for complete information about undo commands.
