This directory contains a cumulative index table (CUM_INDX.TAB) which         
describes the location of all files on the PVO-OIMS volume series.            
In addition, there is a file (INDEX.TAB) which gives the names, associated    
datasets and locations of files on this volume. These index files have        
been provided for database users who do not wish to make use of the           
DITDOS software. The index files are ASCII tables; their columns are          
comma-separated to facilitate loading into most spreadsheet or database       
programs. The index files are accompanied by label files (*.LBL) and a        
format file (INDEX.FMT).
