[amibroker] Passing string via AmiVar

[markedme9]

Hi, 

I am having trouble with passing strings. 
I get access violation error. 

AmiVar AlterSymbol( int NumArgs, AmiVar *ArgsTable )
  {
        AmiVar var;
        var.type = VAR_STRING;
        var.string = (char*)resultsym[11];
        var.val =  EMPTY_VAL;
        return var;
  }

"AlterSymbol",  { AlterSymbol, 0, 0, 0, 0, NULL } 

In AFL fomula it is called as
AlterSymbol ();


I dont get access violation error when I pass a string directly 
var.string = "some text";


Is this the right way to do it?


Thanks
