ctsgnb ... thank you very much I will look at that. I already turned in the program and i am glad i was able to understand all this. I mean i am completely new at UNIX but i really love the idea using the command line. it is so much fun than using just icons and windows. The more I will learn the more I will be stopping on this forum for discussions. thanks.
