The vlist should show a call to Ftrans, which basically does an OPEN and a READ, and caches both for later reuse (subsequent reads on a file open'd earlier don't waste the time of the open). I also believe that the file cache is for 10 files, then the oldest gets closed, and the record cache is for 50 records between all open files. If you do multiple TRANS ops on the same file same record, but different fields, you only pay the cost of search for the field (assuming your file and record are still IN the cache!)
