What are you trying to achieve with a sum of dates?

[PaigeMiller]

What is the question? You never explain, you just throw data at us and give us no clue about what you are doing; please stop doing this. Please ask clear questions from now on and give clear explanations of what you are doing and why you are doing it.

Please explain how input dates of

 3Mar2012 
 5Mar2012

become

06MAY2064

in your "required output using proc sql".

Really? You want a date that is 50 or more years later than the dates given??? And in a different month?
