13. FILE MAINTENANCE<br />

The portable reader software generates a number of files and continuously adds<br />

records to these files. Periodically, records in these files must be deleted so that the<br />

portable reader does not run out of storage area.<br />

The following table describes the rules for deleting records from the files:<br />
