 Hi everyone,
 I am working on my master thesis and I have a data set in three different
 excel files each on different lengths that need to me merged together. I
 saved them as csv since I have some text variables but when trying the JOIN
 function I always get error.  I tried joining them with matching keys  2 by
 2.
 Is there somewhere a  more detailed explanation of the join function?
 Thank you for your help. 
There's a whole chapter in the user's guide.
