Introduction

The selector library selectlib provides functionality to perform table and array processing driven by boolean and arithmetic expressions. The notion of table and array is that of the Data Model defined in the SAS Data Access Layer package dal. Other dal terms such as table column, data set, block, and attribute are likewise used throughout the following sections. Readers not familiar with these notions are therefore advised to consult the dal documentation prior to reading any further.
