				The program use a while loop to get three integers
				Then it sum up the integers and output the sum to the console

				TITLE WhileLoopSum	(WhileLoopSum.asm)

					INCLUDE Irvine32.inc

;This is where we declare all the data information

	.data

;Assign String to getVal
getVal BYTE "Enter the integer: ", 0

;Assign String to output
output BYTE "The sum the integers: ", 0

;Set the sum equal to 0
sum dword 0

;This is the main procedure of the program

	.code
main PROC
	
	;Create a cmd console
	call clrscr

	;Set the loop counter to 3
	mov ecx, 3

	Here we create a whileloop that will loop 3 times
	Inside the while loop we will add up the sum
	Then we will use the compare method and jz condition
	It will jump out of the while loop when the counter hits 0

*


while0:
	   ;Compare the counter to 0
	   ;If the counter is 0, jump to end0
	   
	   cmp ecx, 0
	   jz end0

	   ;Get the integer from the user
	   mov edx, OFFSET getVal
	   call writestring
	   call readdec

	   ;Add the user input to the sum
	   ;Store the value back into sum
	   add sum, eax

	   ;Decrement the counter
	   dec ecx

	   ;Jumps back to the beginning of the loop
	   jmp while0

end0:
	   ;Store the sum back into eax
	   mov eax, sum

	   ;Write the sum to the console
	   mov edx, OFFSET output
	   call writestring
	   call writedec

	   ;Skip line
	   call crlf
