I presume you're citing 6.4.2.3.1 (pg. IV-39), Laura, but that
definition also says "...or a conditional statement that is delimited
by its explicit scope delimiter".  That wording leads me to believe
that a properly delimited add ... size statement  may indeed appear
in a size clause.  Perhaps it would be OK to try to parse the size
clause as part of the inner add (ADD 9) and diagnose the missing
delimiter.
