Introduction

SAS Component Language (SCL) is an object-oriented programming language that is designed to facilitate the development of interactive SAS applications. In SAS/AF software, a frame is controlled primarily by an SCL program, although it is possible to have a fully functional frame that has no associated SCL code. You can add code to a FRAME entry's SCL program to

validate user input
calculate field values that are based on user input
change attribute values of components on a frame at run time
invoke methods of components on a frame
define custom error handling and messaging
provide special user interface features such as menus, graphs, selection lists, font lists, and system information
link to other SAS catalog entries, including other frames
submit SAS programs
read from and write to SAS tables, SAS catalog entries, and external files
interact with other SAS software as well as software from other vendors
