Rookie Programmer has question about the default code

Hey guys, I'm taking a look at the code, and I've got a small question. On this part:
Code:
'========== MAIN PROGRAM =====================================================
'=============================================================================

'---------- Input & Output Declarations --------------------------------------

Output	COMB
Input		COMA
Input		COMC

Output	7	'define Basic Run LED on RC => out7

Output      8	'define Robot Feedback LED => out8	=> PWM1 Green
Output      9	'define Robot Feedback LED => out9	=> PWM1 Red
Output      10	'define Robot Feedback LED => out10	=> PWM2 Green
Output      11	'define Robot Feedback LED => out11 => PWM2 Red
Output      12	'define Robot Feedback LED => out12 => Relay1 Red
Output      13	'define Robot Feedback LED => out13 => Relay1 Green
Output      14	'define Robot Feedback LED => out14 => Relay2 Red
Output      15	'define Robot Feedback LED => out15 => Relay2 Green


'---------- Initialize Inputs & Outputs --------------------------------------

Out7  = 1		'Basic Run LED on RC
Out8  = 0		'PWM1 LED - Green
Out9  = 0		'PWM1 LED - Red
Out10 = 0		'PWM2 LED - Green
Out11 = 0		'PWM2 LED - Red
Out12 = 0		'Relay1 LED - Red
Out13 = 0		'Relay1 LED - Green
Out14 = 0		'Relay2 LED - Red
Out15 = 0		'Relay2 LED - Green
I know this part controls the LEDs, but I've got two questions. First of all, what does "Output" do? Meaning, what does it mean when the code says, "Output 7". And my second question, whats the relationship between "Output 7" and "Out7 = 1"? I take it 1 means the LED goes on and 0 means the LED is off, but how does it know that "Out7" sends to the "Basic Run LED"?
