; At this point our program has added 5 to 2 leaving 7 in c0 and 0 in c1
; but we cannot output this value to the terminal since it is not ASCII encoded.

; To display the ASCII character "7" we must add 48 to the value 7.
; We use a loop to compute 48 = 6 * 8.

++++ ++++  ; c1 = 8 and this will be our loop counter again

]
< .        ; Print out c0 which has the value 55 which translates to "7"!
