SAS® Macro Language 1: Essentials Training in Hong Kong

Before attending this course, you should have completed the SAS Programming 2: Data Manipulation Techniques course or have equivalent knowledge. Specifically, you should be able to

• use a DATA step to read from or write to a SAS data set or external file
• use DATA step programming statements such as IF-THEN/ELSE, DO WHILE, DO UNTIL, and iterative DO
• use SAS data set options such as DROP=, KEEP=, and OBS=
• use character functions such as SUBSTR, SCAN, INDEX, and UPCASE
• form subsets of data using the WHERE clause
• create and use SAS date values and constants
• use SAS procedures such as SORT, PRINT, CONTENTS, MEANS, FREQ, TABULATE, and CHART.

This course addresses Base SAS software.

This course is appropriate for students who are using SAS 9 software.
