It's not for bussiness,so there is no one specific object actually.
As you can see, the problems always be out after some have been solved.
This way I have found if can work,is the fastest way for that,all just because there is no such a function.
And I also know there are lots of sas users want to realize the expression computation,
so the discussion should be multi-win.
And as far as I know, it seems simple,but not easy actually.So it seems only old birds can reply.

Seems everytime someone comes up with a solution you dismiss it because you have a new requirement
you didn't state the requirement up front. Which is probably why many have stopped answering your posts.
We do this for free not because your paying us. The better your question is written the faster you will get a
solution that will meet your requirements.
So let me help you out.... Stop.... really think about all your very very very specific requirements first.
Then list them all out with a very detailed explainantion of what your are starting with and what you
wish to end up with.
