Compiling error

My sketch is an attempt at placing a blink in a section of code for debugging. It looks clean to me but won't compile. The board is working for other projects. I was trying to develop a simple function to be added to a custom library to use during troubleshooting.

collect2.exe: error: ld returned 1 exit status

exit status 1
Error compiling for board Arduino/Genuino Mega or Mega 2560.

The sketch:

int Pin = 13;

void Setup() {
pinMode(Pin,OUTPUT);
}

void Loop(){
Bleep;
return(0);
}

void Bleep(int Pin){
digitalWrite(Pin,HIGH);
delay(1000);
digitalWrite(Pin, LOW);
delay(1000);
}

void Loop(){

It's called "loop"

Also, it's "setup"

Please remember to use code tags when posting code

return(0); <——<<< line not needed.

Bleep; >>>——> change to Bleep(Pin);

delay(1000); At 1/2 Hz, not much of a Bleep.
