Trying to pull records from a .DAT file but my results are blank. I think I have misunderstood how to use file management

Question

So I am trying to pull the records from a file formatted as follows (The reason I am asking this, despite similar questions existing is because I am on a much more "beginner" level than those questions covered.)

(It goes on and on. Each occurence of "ELF #" Is supposed to indicate a new record)

So my code looks like the following, and it just displays blank spaces when I run it. Any suggestions on why I am getting file management wrong? And how should I fix it

       PROGRAM-ID. COBSHL03.
       ENVIRONMENT DIVISION.

         STOP RUN.

Answer 1

You OPEN and CLOSE the file, it looks like you've missed to READ it, likely in a loop checking the defined io-status (which is a PIC XX item).
