A frame does not require an SCL
program. Many components that you can add to a frame are designed
to perform tasks without additional SCL code. For example, you can
add a push button control to a frame and set its
commandOnClick attribute to
end. The END command
then executes when a user clicks the push button. You do not need
SCL to control this control's behavior.
Frame SCL entries do
not have to control every component on a frame. When you create your
own components (or subclass those provided by SAS software), you can
add methods to perform operations. You implement these methods in
an SCL entry that is separate from the SCL entries that are used by
your frames. See
Implementing Methods with SCL for more information.
In addition, communication
between components in your application is possible without frame SCL.
See
Communicating with Components for more information.
