Thanks, it works. However, is there some book,document or whatever that explains all this. I mean, it looks like you are declaring a function that is going to receive 2 string parameters and then it is called with 1 numeric and 1 string. This is not intuitively obvious. In Delphi, I call the same function with 2 pChar parameters. I didn't think C was this forgiving. Again, Thanks :)
