A malleable VI .vim is a VI that is inlined into its calling VI and can adapt each terminal to its corresponding input data type. With malleable VIs, you build a VI to perform the same operation on any acceptable data type instead of saving a separate copy of the VI for each data type. The malleable VIs that LabVIEW provides have orange backgrounds.

Refer to the labview\examples\Malleable VIs\Basics\Malleable VIs Basics.lvproj for an example of using malleable VIs.
