When you submit SAS^® procedures such as PROC PRINT or PROC FREQ in the Program Editor, your Output window might display the following error message:

If this message is displayed, press the F3 key to enable the next procedure to run.

This behavior is expected if you have AUTOSCROLL set to a non-zero number. The AUTOSCROLL option enables you to specify the number of lines printed in the specified window at one time. Once the number of lines is reached, the processing of the current PROC is suspended, enabling review of the new text in the log or output window. After you review the contents of the window, press the F3 key to continue processing until the next specified number of lines is reached. This continues until all the code is processed.

In the Windows environment, the default value for the AUTOSCROLL command in the OUTPUT window is 0. A setting of 0 ensures that no output is written to the window while statements are executing, which provides the best performance. The default value for the LOG window is half the number of lines of the LOG window when SAS is started.

To enable all the procedures to run without having to press F3, issue the following command at the command line in the Output window:

Or do the following:

1. Select Tools ► Options ► Preferences.
2. Click the Advanced tab. You will see the Scrolling Options for Output (default is 0).
   Keep the default settings for the best performance.

Scrolling can increase the length of time that SAS takes to run your program. The less scrolling that the LOG and OUTPUT windows have to do, the faster your program runs.
