	num1 DWORD 10			;Creates "num1" variable which is type DWORD which is a 32-bit un-signed integer. The variable holds 10.
	num2 DWORD 20			;Creates "num2" variable with type DWORD holding 20
	num3 DWORD 30			;Creates "num3" variable with type DWORD holding 30
	num4 DWORD 40			;Creates "num4" variable with type DWORD holding 40
	sum  DWORD 0			;Creates "sum" variable with type DWORD holding 0 because it will be used later to hold the sum of all values.
