HOW TO CREATE A NEW INDEX (ABF.NDX) FILE: 1. Locate and delete all old ABF.NDX files. 2. Run (open) ABFFIND.EXE Once ABFFIND.EXE realises that no .ndx file is present, it automatically creates a new one for you. It only takes a few seconds (depending upon the type of computer you are using, of course.) Thus, is is important that you follow these instructions. Otherwise, if the computer finds an old version of an .NDX file, it will not create a new file and consequently, the data will be all mixed up.
