PROC TRANSPOSE will get you started.

Re: Transform vertical data into horizontal data

Can you tell us what you will do the results?

I ask because there a many tasks that get much harder after transposed to the "wide" form you request.

 

Also, since I have to assume "current_date" means the date the transform is performed, this is a potential problem as running the same code on the same data can yield a different result. Keeping track of such differences may make the project harder to manage.
