| I am trying to fetch previous date in COBOL through CURRENT DATE function - 1 DAY. I don't get the logic or the parameter correct to get the desired result. Can any one please tell me the short code/logic how to go ahead with the function to fetch previous date in COBOL. I am not using DB2 here. |

| There is a link to manuals at the top of the page. Click it, click on the COBOL Language Reference manual, and look up the INTEGER-OF-DATE and DATE-OF-INTEGER intrinsic functions in chapter 7.1. These functions simplify date calculations. |

we dont have option to fetch the previous date but we can do the computation to get the same.
You need to first get the current date and you need to convert it into the julian date and then with help of computation substract one from the julian date i.e. already you have saved.
I hope this helps you.... |

MOVE FUNCTION CURRENT-DATE(1:8) TO WS-CURRENT-DATE.
COMPUTE WS-INTEGER-DATE =
FUNCTION INTEGER-OF-DATE(WS-CURRENT-DATE).
Display 'Previous Date = ' WS-INTEGER-DATE |

I would suggest you test this before posting it! |

Do not test just for syntax errors
Also check if it satisfies OP's requirement too... 
Where is calculation done for getting previous day ????  |

MOVE FUNCTION CURRENT-DATE(1:8) TO WS-CURRENT-DATE.
COMPUTE WS-INTEGER-DATE =
FUNCTION INTEGER-OF-DATE(WS-CURRENT-DATE) - 1.
MOVE FUNCTION DATE-OF-INTEGER(WS-INTEGER-DATE TO WS-PREV-DATE.
Display 'Previous Date = ' WS-PREV-DATE
The above one will give the previous date |
