Kitty,

In this situation, using key= does a lookup based on the variable value.
Using Point= essentially specifies the physical row number of the dataset
which you want to retrieve. The reason it worked in the example you cited
was that ID was equal to the row number in the MASTER dataset.

Hope this is helpful,
