title: COBOL - How to read and export text from .dat files
body: <p>i got a customer who wants to migrate from an old Fujitsu COBOL based system to our system, said that, he wants his old data to be kept in the new system, like products,manufacters, etc.I dont have the COBOL source file, i have: <b>.DAT files</b>, <b>.RDD files</b> and <b>.FDD files</b>. 
  <br><br>
  Apparently the .DAT files are in the <b>INDEXED</b> organization, a sample file output bellow:<br><br>
  <b>FDD output</b>:<a href="http://textuploader.com/kxdv" rel="nofollow">http://textuploader.com/kxdv</a> <br>
  <b>RDD output</b>:<a href="http://textuploader.com/kxdw" rel="nofollow">http://textuploader.com/kxdw</a></p>
  
  <p>I can't simple read the .DAT file in notepad, i've tried the SiberDataViewer but unsuccesfull, also it gets paid to export the data.<br></p>
  
  <p>If there's a way, can i write a program to export all these files to csv,dbf,postgres format?<br> If you are still reading, thank you.</p>
