I was hoping someone could give me a hand working through this... I'm still working out what my tool set is in SAS...
Here is a piece of SQL code that I use to return the weeks active for a customer.
Basically it works out what Week Starting date was the week a custs first order was made, and the last day of the week for their most recent order.
It then works out the difference between the two and gives me an int value.
datediff(wk,dateadd(week, datediff(week, 0, c.FirstOrderDate),0), dateadd(week, datediff(week, 0, LastOrder), 6))
AS 'Weeks Active'
DateAdd doesn't appear to be in SAS.
I've been looking at SAS(R) 9.2 Language Reference: Dictionary, Fourth Edition to try and work out how to make this work... But I'm getting confused.
Has anyone done this before_r

intnx('week',LastOrder,0,'end') - intnx('week',c.FirstOrderDate,0,'Begin') will probably work,
I'm getting . for all fields. So I need to work out why that's happening. Both fields are formatted the same way.
I'll keep chipping away until I work it out.
