How do you read in the variables that you need?
Answer Posted / murray
I believe it is more efficient to use the KEEP statement on
the input data set, as only required variables are read into
the PDV. This is also true for the WHERE statement.
For small data sets the difference is of course negligible,
however it is always good to practice efficient programming.
