Load the Data Set Model. In this example, the data set model object is being used as a stand-alone object. Therefore, if you are using SCL similar to this with a data form object or data table object, you should omit the LOADCLASS and INSTANCE functions. 
INIT:
  dcl list collist={'sex', 'descending', 'name'};
  datcl=loadclass('sashelp.fsp.datast_m.class');
  datid=instance(datcl);
