Hi,
I was analysing a program ans found that calling program which should pass two variables with Using Clause is passing on only one with one comma as given below:-
CALL 'RS0MADR3' USING REAS-WINDOW-ALPHA-TEMP ( 1) ,
But progrm RS0MADR3 is recieving two variables in linkage section.
Is there any default value after comma which is passed if we don't give it explicitly.
thanks
Saini |

nope I am compiling it and it is not giving any compilation error.
below is the actual code :-
| Code: |
CALL 'RS0Y4DR3' USING WS-COMPARE-DATE , REAS-WIND-OFF
MOVE 901231 TO REAS-WINDOW-ALPHA-TEMP ( 1)
CALL 'RS0MADR3' USING REAS-WINDOW-ALPHA-TEMP ( 1) , --------> I am talking about this line
* IF (WS-COMPARE-DATE GREATER THAN 901231) AND
IF (WS-COMPARE-DATE GREATER THAN REAS-WINDOW-ALPHA-TEMP ( 1)) AND
(WS-RETIREMENT-YEARS LESS THAN 75)
CALL 'RS0Y4DD3' USING WS-COMPARE-DATE , REAS-WIND-OFF
PERFORM 4000-SAFE-HARBOR
THRU 4000-SAFHRBR-EXIT
GO TO 2310-PREPARE-RECORD-DATES-EXIT
ELSE CALL 'RS0Y4DD3' USING WS-COMPARE-DATE ,
REAS-WIND-OFF. |

What is the value in the received field? Is it spaces? |

IIRC, the called program needs to check the address of the second parm before using it. If it is null, do not reference the data area.
BTW, a comma on a COBOL line means nothing. |

if RS0MADR3 (the CALLed program)
does not insure that there is addressability to the second parm,
but instead references to the second parameter are made as if the parm was provided,
you have lost a source line in the CALL.
If RS0MADR3 does indeed insure addressability of the second parm, then the CALL syntax, though irregular, is correct. |

Hi sunil!
The list of the parameters is tranlated to a list of words(4 bytes), each word contains the address of the corresponding par. the last word in the list contains in the high order bit, of the first byte from left, is on.
so everything is perfect if the called program check this bit to look if this is the last parameter passed to it otherwise it will get garbage.
best tiding. |
