integer was wrong padded§ length

or rather right (2 as should be and will be)
but currently we use next AND value + type means 3, rounded 4

we use next OR value)

Torsten Ruger
8322fca7b3
give labels an integer that will end up being the position at runtime
...
Since integers are first class objects, we need to use an integer object
as the return address. The actual address can not be stored in an
instance variable since it is not an object.
The address is unique to the label and never changes after positioning
(using the int is next up)

That is what the interpreter works on.
