The 1301DLY.zip file is a data/info file that will update the database that came with the XYZ Demo self-extracting file xyzd0195.exe that expires on Jan.31/95. To update your database files: 1) You must first run XYZ after extracting and installing the demo from xyzd0195.exe. Read the xyzd0195.readme text file on how to do this. You should then rename the DLY.new file that comes with the demo to DLY and run the XYZ demo again. This will update your database to Dec.30/94. 2) Unzip the 1301DLY.zip file - Copy DLY file to the C:\XYZ directory. 3) When you run the XYZ Demo again, your database will be automatically updated to Jan.13/95, and you will get the Roll-over prompts. If you have manually updated the database files and have made errors, these errors (upto Jan.13/95) will all be corrected with this updating.
