The Select Number Variable and Select Text Variable property
view are very similar in their appearance and operation. Both
consist of a list that displays the available variables in the
variables set (or sub-set) selected in the Base Object drop-down
list.
The Base Object drop-down list contains variable sets and sub-
sets. The drop-down list acts as a path to object and object sub-
sets. The default option is the <Form’s Base Object>.
Notice the angle brackets around the Form’s Base Object. This
indicates that the options appearing below it in the drop-down
list are all variable sub-sets. For example, the options that
appear below the Form’s Base Object option are all variable sub-
sets of the DefaultView form. If such a tributary option is
selected, the drop-down list hierarchy immediately changes.
While the selected option appears in the field, when the drop-
down list appear, the selected variable sub-set appears just
below the Form’s Base Object option surrounded by square
brackets. Drop-down list options that appear above the current
selection allow you to return to a higher level of the variable
hierarchy. The options that appear below are in turn sub-sets of
that selection. The display field that appears above the list
displays the variable set path.
