I found it. Apparently there is no functional equivalent to DISPLAY_FOLDER which exists in AS 2005.
Thanks.
This is incorrect, there IS a functional equivalent in 2005.
While you can't specify DISPLAY_FOLDER in the script itself if you click on the "Calculation Properties" button in the tool bar while in the calculations tab of the cube designer it will pop up a dialog box that lets you specify the DisplayFolder and AssociatedMeasureGroup
properties for calcuated measures. This button is usually found to the right of the form view/script view buttons.
