Forced Date Routine Processing

I’m trying to process a RUNDATE = 2009-08-07 into my COBOL code via a PARM-DATE Link. That date comes in… now I try to place it in the following piece of code: EXEC SQL SET :WS-PREV-WK = CHAR(DATE(TMP-DATE)- 7 DAYS) END-EXEC. What am I getting '0001-01-01' returned?

Thanks. We'll let you know when a new response is added.

Why not do the date manipulation using the COBOL / CBLLE code only?

01 ISO-TODAY
FORMAT DATE “@Y-%m-%d”.

01 ISO-LAST-WEEK
FORMAT DATE “@Y-%m-%d”.

MOVE FUNCTION SUBTRACT-DURATION
( ISO-TODAY DAYS 7 ) TO ISO-LAST-WEEK.
