  <p>So, I know, how I can make a program to read this in C/C++ or in C#, but, I try to make in Cobol, just for study....</p>
  
  <p>But, I don't know what the command I need to use to open the file with this style ( I just know the:</p>
  
  <pre><code>ORGANIZATION IS LINE SEQUENTIAL.
  </code></pre>
  
  <p>I think, exist a another command to open with custon instructions... i don't know...
  So, btw, how I can open the file and read the informations ??</p>
  
  <p>( i just need to read the line 1 on time, and, I need to read the line 2 and 3 always paried ... 4 and 5 &amp;&amp; 6 and 7 &amp;&amp; 8 and 9 ... )
  and, I whant to show that information with DISPLAY ( just for study )
  Thanks :)</p>
