To save the serial number to a file set procedure to :duflp:miscapi.prg f = new file() f.create('serialno.txt') f.puts(getSerialNumber()) f.close() close procedure :duflp:miscapi.prg To check the serial number f = new file() if f.exists('serialno.txt')     f.open('serialno.txt')     cNo = f.gets() endif ?cNo f.close() You need to add code to deal with the serialno.txt not found or with the incorrect serial number returned.
