Hi guys, can someone help me?. While I was studying functions I came across a situacion, example: function soma(n)  
soma(1,n, positive).  
What I didn’t understand is the use of the comma when the function is called. Could someone explain to me why using a comma when a function is called and the advantage it brings. Thanks 🙂

It separates input arguments, it is pretty standard in programming and not specific to Julia.

You must be a [Scheme](https://en.wikipedia.org/wiki/Scheme_(programming_language)) programmer? 😉

Are you coming from Stata by chance?

This is just the syntax that Julia uses, similarly to C and related languages.

If these things are new or puzzling to you, please consider reading the manual from the very beginning. Function calls are discussed in
