DCL P_OUT PTR;
DCL OUTPARM CHAR (10) BASED (P_OUT);
DCL PGM_B ENTRY (CHAR(12),PTR) EXTEPNAL;
CALL PGM_B (INPARM,P_OUT);
IF OUTPARM = 'YES' THEN
DO;
INPARM = 'FOLLOW ON';
CALL PGM_B (INPARM,P_OUT);
END;
ELSE
DO;
INPARM = 'NORMAL CALL';
CALL PGM_B (INPARM,P_OUT);
END;
PUT SKIP LIST(OUTPARM);
END;
PGM_B: PROC(INPARM,P_OUT);
DCL INPARM CHAR (12);
DCL P_OUT PTR;
DCL OUTPARM CHAR (12) STATIC INIT(");
