      The INDEX directory contains an index for this volume (INDEX.TAB)       
and a PDS label for the index (INDEX.LBL).                                    
                                                                              
      The INDEX.TAB file is an ASCII file.  Each line (or record) in          
INDEX.TAB contains information about a data file in this PDS archive          
volume.  For data files with attached PDS labels, the data file itself        
is listed in INDEX.TAB.  For data files with detached PDS labels              
(*.LBL), the detached PDS label is listed.  The last two bytes of each        
record are an ASCII carriage-return line-feed pair which delimits the         
line.                                                                         
                                                                              
      Each line in the INDEX.TAB file is made up of comma-delimited           
fixed-length fields.  Some of the values in these fields are enclosed         
by double quotes.                                                             
                                                                              
      The INDEX.LBL label file describes the format and content of the        
INDEX.TAB file at the byte level.
