Hi Guys,
Plzz help me out in this!!!!!!!!!!!!!!!!

I have a file which runs in the back ground using crontab for every monday at5 P.M. The problem is inside the file ...

This is a sample content of a file

Update the current and previous week: (Sunday to Sunday)
%let wk_curr=20070930;
%let wk_prev=20070923


Here i need to change the dates regularly i.e. every week. before the job starts running on monday..

(20070923 is a sunday and also 20070930 is a sunday)

so wen the job runs for th next time, i need the dates to be like

%let wk_curr=20071007;
%let wk_prev=20070930;


there is no problem if the dates are changing within a month but in the case of last date of the month ,its not getting updated properly..


plzzz guide me in this as it s very urgent


Regards,
Anand
