Daniel, In LabVIEW 6.1 there is an example called �Parse Arithmetic Expression.vi� Located in the strings.llb of your :
Program Files\National Instruments\LabVIEW 6.1\Examples\General folder. This would be a good start. I have written a script interpreter for LabVIEW and it�s not trivial enough to give away. But you can do what you want and handle the declaration of �variables� including unique names. I would strongly suggest you �think outside� the box � typing expressions is very DOS and those days as we all know are gone!. Surely you can have a simpler interface. Also, it�s easy for �humans� to make mistakes entering complex text syntax � another reason for a better graphical interface.
