Marking all your VI's reentrant might give some increased processing speed but as each instance of the VI has it's own memory space, so depending on what you're doing making all your VI's reentrant can cripple you with memory requirements (especially with low RAM systems like FP controllers). I would also think that re-entrancy here is only for testing "as near to optimum", presumably building a VI into an EXE would achive the same increase in performance as is achieved with reentrant=TRUE, as the UI and debug code are removed then. Is that correct Jim? cheers, Alex.
