;puting symbolic constants in an array of DWORDS

.code
main PROC

	;32 bit registers should be used
	mov eax, week							 	  ;eax = 1
	mov ebx, week+4								;eax = 2
	mov ecx, week+8								;eax = 3
	mov edx, week+12							;eax = 4

	;in order to reach the next element of the array
	;we must inciment by 2 because it is a WORD array
	;16 bit registers should be used
	mov ax, week2						 		  ;ax = 1
	mov bx, week2+2								;bx = 2
	mov cx, week2+4								;cx = 3
	mov dx, week2+6								;dx = 4

	;in order to reach the next element of the array
	;we must inciment by 1 because it is a BYTE array'
	;8 bit registers should be used
