The Value Set Management dialog displays the value sets and associated values in a tabular format where the rows are value sets and the columns are variables. Choose the button on the Variables window to display the Value Set Management dialog.
You can edit the Expression cell to change a variable's value for the associated value set. To create a new value set in this dialog select one or more rows and choose the button. To remove a value set, select one or more rows and choose the button or press Delete. A value set can be renamed by editing the contents of a cell in the first column.
