One of the great features of LabVIEW is that VIs, in general, are not OS or version specific. Every time you save a VI, the block diagram is compiled into machine language on the computer that is saving the VI. This machine language becomes the "code" section of the VI, mentioned above. Machine language is compiled code, and is specific to the particular version of LabVIEW, as well as the OS on which it was compiled.Based on that information, once a VI is saved without diagrams:
In LabVIEW 7.1 or previous, you could select File»Save with Options and save the VI without its block diagram using the dialog which pops up.
