Closing VSAM Files

   Use the CLOSE statement to disconnect your program from the VSAM file.  If

   you try to close a file that is already closed, you will get a logic

   error.  You should check the file status key after each CLOSE statement.

   In the event that you do not close a VSAM file, COBOL will automatically

   close the file for you, giving you a warning-level diagnostic message.

   See "Automatic Closing of Files"  details.
