Jakubi, thanks for the comment, I understand the fundamental difference between the two. I was wondering if I can do what Robert did with the seq command. I figured it out! what's cf ? thanks

Thanks Robert, it worked! why do you have to use for - do loop instead the seq command? is it possible to do it that way? I'm just curious thanks again

I have 2 questions for you guys: 1. how do I write the file path in the mac version? readdata("C:\\Maths\\Maths 11\\example.txt",[integer,float,float]); this is in Windows? what's the equivalent of this in mac 2. if I have multiple sequential files like data.1 data.2 data.3 ... data.n how can I read all of them without repeat the command n times thanks H
