So I have two sets of dates one is Start_Date the other Closed_Date.  Start_Date is always populated, however Closed_Date can be null.  I have a formula in Excel that does the job, but I wanted to migrate this into SAS.

 

Excel Formula: =IF(I5="", TODAY() - H5,I5-H5)

 

So what I am trying to do is if Closed_Date is null then take today's date and subtract the Start_Date which will give me days open.  However if the Closed_Date has a value, subtract that value from the Start_Date to give me days open.

 

How would I transform this excel code into SAS code?

Something like this in a DATA step should work:

 

if closed_date > . then days_open = closed_date - start_date;

else days _open = today() - start_date;

 

There are minor efficiency considerations that could avoid calling the TODAY() function so many times.  But that would be way down the list of priorities.

Thank you this is perfect.  I had to play around with the dates a little, but once I did the count worked perfectly.

 

 

data work.test;
 set work.extract;
  format closed_date start_date date9.;
 
   closed_date=datepart(closed_date);
   start_date=datepart(start_date);


    if closed_date > . then days_open = closed_date - start_date;
    else days_open = today() - start_date;
run;
