I found this cool free c, c++ scripting environment and thought it might be of interest to anyone trying to add a scripting language that is not C# or VB, to their application. This also has a very good license agreement so that means you can use it in commercial and non-commercial applications. There is also a program called root on this page but the cint is all you need to be able to use it at the MsDos command line. I even ran a lot of the little demo programs I have wrote to answer peoples questions on this list and have only had trouble with one and that is because it uses Win32. I know it will work but I need to set something up before it will. So anyway if your interested here is the link. http://root.cern.ch/twiki/bin/view/ROOT/CINT Ken
