Call dynamically created function name

Doesn't look like, I got the same error even if I set the exact amount of elements

Then I would suggest the error is the fault of the simulator.

The following code appears to work exactly as expected

void Func0()
{
  Serial.print ('G');
}
void Func1()
{
  Serial.print ('A');
}
void Func2()
{
  Serial.print ('T');
}
void Func3()
{
  Serial.print ('C');
}

void (* funcs[])() = {Func0, Func1, Func2, Func3};

void setup() 
{
  Serial.begin (9600);
}

void loop() 
{
    funcs[random(4)]();
    delay(1000);
}

But back to main topic: So there is no way to call a function name which as been created dynamically by a string?

I can't think of a compiled language it would be possible with.

Tell us what you want to do, not how you think it should be done.
