You want the windows xp machine to access the internet through the windows 2000 machine? So the windows 2000 machine is going to be the host and the windows xp machine is going to access the interent *through* the windows 2000 machine. Right? Need to have that clarified, thanks.
The primary purpose of the DATA statement is to give names to constants; instead of referring to pi as 3.141592653589793 at every appearance, the variable PI can be given that value with a DATA statement and used instead of the longer form of the constant. This also simplifies modifying the program, should the value of pi change.
