	; =================================================
	; We can't directly print number on terminal in assembly.
	; To print any digit, first we have to convert it into ASCII code.
	; actually, assembly prints all character/Digit/Number/Word According
	; To ASCII code Table.

	; Let's print
	mov eax, VName		; Load Memory address
	call _printline		; call _printline Routine

	; let's print anoter character
	mov eax, VSingle	; Load Memory Address
	call _printline		; Call _printline Routine

	; Exit
	jmp _exit	; Exit routine
