Sashelp Data Sets

SAS provides over 200 data sets in the Sashelp library. These data sets are available for you to use for examples and for testing code. For example, the following step uses the Sashelp.Class data set:

proc reg data=sashelp.class;
   model weight = height;
run; quit;

You do not need to provide a DATA step to use Sashelp data sets.
