Subject:      loading two character variables into a list and ...
Comments: To: sas-l@uga.edu

The following code creates a SAS dataset with two variables.
The first variable is used later in a combo box control. (drop down list box)
The second is the location of the value of the first variable.
The intention is to load a List with the first variable and create a second
List for the location. The user selects there document and it opens. The SCL
code loads one variable into the List. The user would select the document to
view by clicking a choice shown in the combo box control. Is would likely be
simpler to use only one List containing both variables. How is that done?
