(scrSetListFilter gScreen "*U")

The current screen lists all the non equipped items.

            dataFrom=   "station"
            list=      "*"
            (not gMargin)
               (scrSetListFilter gScreen intComputeSellPrice) ; Price is calculated individually by item.
            (isfunction gMargin)
               (scrSetListFilter gScreen gMargin) ; expression is function
            (scrSetListFilter gScreen "*") ; expression is criteria string
