RE: Using Subdur

Unless you program really need to use the job date (which is what the UDATE is), the current system date is normally easier to deal with.

myDateKey = %dec(%date() - %days(6) :*ymd)

I'm sorry, I misrepresented the question. I  see how to get the various days here. But I have to read a file that has the dates as conventional Numeric YYMMDD. This is the problem.

They are date fields but how to I get UDATE into this, since it is not
a date - field? I need udate to know what my starting point is.

Actually SUBDUR can also give you a date by adding or subtracting
*DAYS,*WEEKS,*MONTHS, *YEARS from one date To obtain Mondays date
Assuming SUNDAYSDATE is a date field MONDAYSDATE is a date field then
C Sundaysdate subdur 6:*Days MondaysDate

HI In this case, I have to take a report and make it a weekly. I
would have this set to run on Every Sunday. I am not quite sure how
to get to the previous Monday. Subdur only tells me how many days
between 2 dates. I need to go back what 6 days and cap it for 4 more.

Also the dates in my file are YYMMDD. I would use the UDATE which is

MMDDYY..

Any help would be greatly appreciated.
