Under Windows, the default
value for the AUTOSCROLL command in the OUTPUT window
is 0 (meaning that no output is written to that 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.
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 that your program
runs.
You can also set scrolling
options in the Preferences dialog box Advanced
page.
