U3 - CP/M PLUS UTILITY FOR RECOVERING ERASED FILES AND FOR
CHANGING THE USER AREA OF A FILE. This program is based on
UNERASE.COM in the public domain. It has been modified to
work with CP/M 3.0 and later, to change the user area of a
file, and to accept ambiguous files names. It currently
works with sector sizes of 128, 256 512 and 1024 bytes. It
is placed in the public domain by Advanced Logic Systems for
public use. Advanced Logic Systems makes no warrantee on the
operation or use of this program or its applicability for any
given application.

U3 DOES NOT DOES NOT WORK WITH VERSIONS OF CP/M PRIOR TO CP/M 3.0

The U3 command line takes the form:

		U3 [d:]afn.aft [user area]

If no user area is specified U3 recoverers all erased files on
drive d: (or the default if d: is not specified) matching
afn.aft and places them is the current user area. If a user area
is specified U3 moves all files in the current user area on
drive d: (or the default if d: is not specified) matching
afn.aft to the specified user area.

Versions 1.01 and 1.02 of U3 were prepared by R. Saeks from
Gale Wolfenbarger's code for version 1.00. Comments regarding
