HEADER contains the text and text alignment for report headings. You can also limit the ZIP/Postal Codes you want to be processed with the HEADER parameter record.
GeoTAX bypasses any ZIP/Postal Code that is lower than the one you define in positions 60-65. As soon as GeoTAX encounters a ZIP/Postal Code higher than the one you define in positions 67-72, it stops processing. This is why we strongly suggest that you sort your input file in ZIP Code or Postal Code sequence (ascending order).
