Dear Dave,

As someone pointed out to me, I used %put and not put - hence, I was wrong
sorry.

And yes, you are correct about the order of the SET and IF statements not
providing the same results.

I'll try to come up with a good explanation unless someone already has.

Sorry for any confusion I am have caused you,
Charles Patridge
