The Libraries list shows the SAS librefs that are currently allocated in your SAS session. Initially, the SASUSER library is selected, and the SAS Data Sets list shows the data sets available in your SASUSER library.

In the Libraries list, select the row that starts with SASHELP. The Data Set Selection window now lists the data sets in the SASHELP library, as shown in Figure 56.6.

Use the vertical scroll bar on the SAS Data Sets list to scroll down the list until the data set CITIQTR appears. Then select the CITIQTR row. This selects the data set SASHELP.CITIQTR as the input data set.

Figure 56.7 shows the Data Set Selection window after selection of CITIQTR from the SAS Data Sets list.
