Mql5 Identical Global Varaibles

 

Hi, I hope you are all doing great. 

I have been learning more and more about Mql5 programing language for the past few months, but there is one thing that keeps confusing me. It is about some Global variables:

_Symbol          Symbol()
_Point           Point()
_Digits         Digits()

Correct me if I'm wrong, but so far, every time I use them they all return the same thing. So, my question is why have two identical Global variables? Is there some context where one can be used and the other can't???

Tanks?
