There have been a couple of different approaches to 
undeleting records, and the key is that the records are 
only recoverable if the file has not been reorganized, and 
the records have not been recycled in any other way.

One approach has involved unsupported hacks in a patched 
*PGM that won't run above a certain security level, while 
the other approach has involved (if memory serves) saving 
the file to a *SAVF, manipulating the *SAVF, and then 
restoring it.

If memory serves correctly, Dave McKenzie came up with it, 
and you can read all about it just by searching for UNDEL 
in the MI400 and MIDRANGE-L archives.
