Writing the data to the file is done within the while loop. This way I can limit the number of data points within a file. When taking data for real (rather than for testing and calibration) that will likely be a week or so worth of data. I am considering changing from a limited number of records in the file to creating a new file at a week or month boundary. But as it stands, I am not reopening the file within the loop, except that the poster fat16lib says that print closes the file each time, so I need to change the file opening command to avoid that. -Denis _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
