Thanks everyone for your replies. Oh yes, I've tried it. In fact, I hate to admit that I have been trying to get it to work for 6 straight hours now. I think I may have a different problem with a parameter that the final binary requires. Anyway it took me a while to finaly come here and ask. I try to figure things out on my own as I am trying to rely on google and the perl docs. Buut.. I must be slow because I have read and re-read the docs on it and didnt quite get it. But I think I have a better understanding now thanks to everyone here. : )
