Overview
Introduction
This chapter considers direct access technique. For
example, you might want to select a subset based on a value within
your data, such as a CustomerID number. You can accomplish this action
by creating an index on your CustomerID variable using the INDEX=
data set option. A WHERE clause can then use this index. By accessing
the desired observations directly, rather than all observations sequentially,
your program runs faster.
