1.主程序ST030.COBOL.SOURCE(LAB13)
IDENTIFICATION DIVISION.       
PROGRAM-ID. LAB13.             
ENVIRONMENT DIVISION.          
DATA  DIVISION.                
WORKING-STORAGE SECTION.       
77   A    PIC   99  VALUE  2.  
77   B    PIC   99  VALUE  3.  
77   C    PIC   99.            
PROCEDURE DIVISION.            
S1.  CALL 'SUM1' USING A, B, C.
    DISPLAY 'C=', C.           
    STOP  RUN.                 
END PROGRAM LAB13.                 

2.子程序ST030.COBOL.SOURCE(LAB06S)

END PROGRAM SUM1.                    
3.编译连接运行程序ST030.COBOL.SOURCE(LAB06CON)
//ST030A JOB 2008,'L.G.Y',CLASS=A,MSGLEVEL=(1,1),NOTIFY=ST030 
//STEP1 EXEC PROC=IGYWCLG                                     
//COBOL.SYSIN DD DSN=ST030.COBOL.SOURCE(LAB13),DISP=SHR
