Q: Functions that returns more params and window without the symbol?

[CORNELIUS]

I have 2 questions about MT4 and MQL4:

1. Can the function return more params than one? I know it is possible to do it by merging params into one string but maybe is better solution?

2. Is it possible to open in MT4 a window without choosing the symbol? The chart would be drawn by indicator.

Thank you,

about first question, you can send parameters byrefrence like this :

void Myfunction(int& a,int& b)
{
a=10;
b=24;

}

int a,b;
Myfunction (a,b);
Alert(a);
Alert(b);
