Carl,I have tried this undo/redo, but as Xy4 is less usable for my purposes (I need a simplistic formatting system that can be easily converted to other formats, like Ventura or XML), it has been a non-starter. Xy3/NB3 has a backup option which makes a BAK file when a CALLed file is first saved (default setting BK=1). As this is not very helpful as an undo device, I have replaced my save routine with a routine which makes a BAK file every time a save command is issued. This kind of routine could be augmented to make a succession of backups to cover all disk commits during a session. That said, I find that a normal BAK file has been sufficient.

This is essentially what Robert's Undo|Redo does for Xy4, with the added convenience that it can do the job automatically, in the background. (It's part of U2.) I also have routine called RD that saves all or user-selected block deletions to disk. These tools are a pretty good way of retracing your steps in Xy, but they do not approach the convenience of Ctrl-Z/Ctrl-Y in Windows. As wonderful as it would be to have that in Xy, I'm doubtful that it's attainable in a DOS environment -- though I'd love to be proved wrong. -- Carl Distefano cld@xxxxxxxxxx
