IBM DOS/VS COBOL permits an optional clause in a SELECT statement (also called a "file-control-entry"):
     {FILE-LIMIT IS  }  limits-1  [limits-2] ...
     {FILE-LIMITS ARE}
            	 Here limits-1, limits-2, etc., are phrases of the form:
     {data-name-1} THRU {data-name-2}
     {literal-1  }      {literal-2  }
            	 IBM DOS/VS COBOL treats this clause as a comment. ACUCOBOL-GT ignores it in the IBM DOS/VS COBOL compatibility mode.
Put the FILE-LIMIT clause in any convenient spot after the ASSIGN clause.
