| Also, you need to be more specific. 6 months ago, same day of the month? What about leap year? |

Meenakshi ,
U can use the following code..............
| Code: |
IF FORMAT-DATE-MM < 7
SUBTRACT 1 FROM FORMAT-DATE-YY
ADD 12 TO FORMAT-DATE-MM
IF FORMAT-DATE-YY = 00
MOVE +99 TO FORMAT-DATE-YY
SUBTRACT 1 FROM FORMAT-DATE-CC
ELSE
SUBTRACT 1 FROM FORMAT-DATE-YY.
SUBTRACT 6 FROM FORMAT-DATE-MM.
IF 30-DAY-MONTH IN FORMAT-DATE-DATE
AND FORMAT-DATE-DD > 30
MOVE 30 TO FORMAT-DATE-DD
ELSE
IF FEBRUARY IN FORMAT-DATE-DATE
IF LEAP-YEAR IN FORMAT-DATE-DATE
AND FORMAT-DATE-DD > 29
MOVE 29 TO FORMAT-DATE-DD
ELSE
IF FORMAT-DATE-DD > 28
MOVE 28 TO FORMAT-DATE-DD |
Where the date can be defined as :
| Code: |
05 FORMAT-DATE-DATE.
10 FORMAT-DATE-CC PIC 9(2).
10 FORMAT-DATE-YY PIC 9(2).
88 LEAP-YEAR VALUES 00 04 08 12 16
20 24 28 32 36
40 44 48 52 56
60 64 68 72 76
80 84 88 92 96.
10 FORMAT-DATE-MM PIC 9(2).
88 FEBRUARY VALUE 02.
88 30-DAY-MONTH VALUES 09 04 06 11.
10 FORMAT-DATE-DD PIC 9(2). |
Hope this will help you. |
