END_OBJECT = TEXT END INDEX Directory Contents The INDEX directory contains tabular index files describing the content of the data set. Each tabular index is accompanied by a detached PDS label. The index files present depend upon the files in the data set. Required files present in all data sets: --------------------------------------- INDXINFO.TXT - The file you are reading. INDEX.TAB - Main INDEX table listing all label files INDEX.LBL - PDS Label for the main INDEX table Notes on Using the Index Tables ------------------------------- Each index table contains one row (record) for each data product on the volume. The table is formatted so that it can be read directly into many data management systems. All fields are separated by commas and character fields are enclosed in double quotation marks ("). Character fields are left justified and numeric fields are right justified. Each record ends with ASCII carriage return and line feed characters. This allows the table to be treated as a fixed length record file on computers that support this file type and as a normal text file on other computers. The PDS label file for each table describes the content and structure of the fields in the index table. This description includes the name of each field, its format, and a brief definition. The values for start byte and number of bytes listed in the label file do not include commas between fields or quotation marks surrounding character fields.
