There is difference between how SAS handles IF and WHERE
conditions. The 'WHERE' condition is applied on data before
they enter Program Data Vector (PDV) and in case of 'IF' it
is applied after data comes out from PDV. Now, if you have
created a variable in the same data step using
Where : the created variable will not be applied condition.
IF: the created variable will be subjected to the condition
applied.
