On DOS 3.3 disks the file is an empty text file whose name shows the date in the format
LAST UPDATE M/D/YY. For example, on the Assault on Dolni Keep disk the file is named
LAST UPDATE 11/8/89.
On ProDOS disks the file is saved in Applesoft BASIC and named in the format
REV.DMonYY.LC. For example, the ProDOS version of Dolni Keep has a file named
REV.21MAY91.LC. Unlike the DOS 3.3 text file, the BASIC file in ProDOS is not empty and includes the club's address, the adventure's name and author, and the date of last revision.
