File control in COBOL

Note: I'm a taking a class.

In this code, there seems to be an issue with the following segment of code. Can you tell me what is going on?

*                                        
 FILE-CONTROL.                          
     SELECT PRINT-LINE ASSIGN TO PRTLINE.
*-------------                      
 DATA DIVISION.                    
*-------------                      
 FILE SECTION.                      
 FD  PRINT-LINE                    
     LABEL RECORDS ARE OMITTED      
     RECORD CONTAINS 121 CHARACTERS.
 01  PRINT-REC          PIC X(121).
*
