SAS Component Language: Reference

Introduction

Version 8 SCL provides many object-oriented programming features such as class and useclass syntax, method overloading, and interfaces. This tutorial demonstrates how to use many of these new features by creating a class-based version of a simple data input facility that is based on traditional SCL library functions.

The tutorial is organized in sections by level of difficulty, with Level Zero being the most elementary and Level Five the most challenging. A beginner should work through sections Zero, One, and Two. The remaining sections can then be reviewed as the user progresses. For example, a beginner may want to return to the tutorial after gaining additional experience with the basics. A user who is more experienced in object-oriented programming may want to work through them at once. Level Five should be reviewed by all users because it contains an example that shows how the SCL class syntax can be used with SAS/AF software.
