(j3.2006) Corrigendum 2

[Van Snyder]

While looking at Corrigendum 2, I noticed that the revised C566 at
[104:26-27] begins "A <data-stmt-object> that is a <variable> shall be a
<designator>."

Would it have been simpler to change R536?

R536 <data-stmt-object> <<is>> <designator>
                        <<or>> <data-implied do>

We don't need to change the corrigendum, but if this is possible, in the
next revision we ought to consider simplifying the post-Corrigendum C566
and changing R536 instead.
