The numbers in the IFS Compose plugin are used as so called ordinal
numbers, i.e. they don't refer to a count of certain objects but to a
order of the objects. As you can see at e.g.
    http://www.webster.com/mw/table/number.htm
ordinal numbers start at 1 and there is no such thing as an ordinal
number 0.

Hence the number "0" in the ancient version of the IFS Compose plugin
was a bug and has been corrected for the Version 1.2.

If you want to learn more about ordinal numbers have a look at
