Every array has a long integer value associated with the array that represents the selected element of that array. You can use this long integer value as a variable to pre-define what the user has selected from the array through the interface. This long integer variable has the same name as the array itself.

For example:

ARRAY TEXT(arrNames;4)
arrNames{1}:=Bob
arrNames{2}:=Joe
arrNames{3}:=Tom
arrNames{4}:=Sue

arrNames{arrNames} refers to the contents of the element of the array.

If the user chooses Joe from the form, then arrNames = 2 and arrNames{arrNames} = Joe.
