I am working on a huge dataset and want to create a process whereby a list of customers is created who visited hospital in last six month. Everyday (or every week) this list will be extracted which will have customers for last six months from today (Day I ran the code ) i.e system date. Current I have Visit_date in 21122011:07:35:05 format (DD/MM/YYYY:Hours:Minec).
What will be your approach? Will you use INTCK to extract number of months and then use if condition to extract customers where INTCK value is eq to 6?
Any suggestion will be most useful. Thanks

Compare with the same day of the month, six months ago :
format visit_day start_day date9.;
Visit_date = "21122011:07:35:05";
visit_day = input(visit_date, ddmmyy8.);
start_day = intnx("MONTH", today(), -6, "SAME");
include = visit_day >= start_day;
proc print; run;
