You know, maybe I am making too much of this. I am thinking - if a jre
is there, why not just run the program as a java program?! Just have
the client load the jre and that should do it. Am I not correct?
Having thought the whole C thing over, python is still the way to go.
I apologise for being so nasty. I really did not mean to offend
anyone. You took time to respond and I do appreciate it.

Thanks!!
