8.1.4 Fields

Each row in the array shall consist of a sequence of fields, with one entry in each field. For every field, the ANSI FORTRAN-77 format  of the information contained, location in the row of the beginning of the field and (optionally) the field name, shall be specified in keywords of the associated header records. A separate format keyword must be provided for each field. The location and format of fields shall be the same for every row. Fields may overlap. There may be characters in a table row that are not included in any field.
