Subject: How to add new var to existing data set? (sounds easy)
Content-Type: TEXT/PLAIN; charset=US-ASCII
My question sounds easy. I got the problem several months ago and I
couldn't find the solution even I can use SQL. Now I am brave enough to
I have a date set (e.g. mgmt.puf) and I want to add new variable c to this
c=a+b; (I may not have such a explicit formula, just to show what I
want) where a and b are already in mgmt.puf.
What should I do?
Thanks in advance,
