Summary

In this chapter, you were introduced to the fundamentals of the SAS/IML language. The basic data element, the matrix, was defined, and you learned several ways to create matrices: the matrix literal, CALL statements that return matrix results, and assignment statements.

You were introduced to the types of statements with which you can program: commands, control statements for iterative programming and module definition, functions, and CALL subroutines.

Chapter 3 offers an introductory tutorial that demonstrates how to build and execute a module by using SAS/IML software.
