The ODL object descriptions in this file describe the data fields in each row of the table. The table is formatted so that it may be read directly into many data management systems on various host computers. All fields (columns) are separated by commas, and character fields are enclosed in double quotation marks. Each record consists of 512 bytes, with some spares (blanks) near the end, and with a carriage return/line feed sequence in bytes 511 and 512.
