make "letterbox 7	puts a seven in the box called letterbox
make "letterbox :letterbox + 3	letterbox will now contain 10 ... check by typing show :letterbox
make "newbox :letterbox	the box called newbox will have 10 in it also
make "r random 5	the box called r will contain 0,1,2,3 or 4 - the only way to find out which, is to type show :r
