I've committed the attached patch as obvious. My previous
patch was too strict (and incorrect) in the interpretation
of
R837 data-stmt is DATA data-stmt-set [ [ , ] data-stmt-set ] ...
The previous patch required whitespace after DATA, but it seems
that it id valid to do 'DATA(x(i),i=1,2)/1.,2./' where the implied
do-loop nestles up against DATA.
