Subject: Ambiguity in Z.100 11.12.2.4 concrete graphical grammar

The binding of the clauses in the sentence:
The <expression> in <return> or <return area> shall not be omitted if the
enclosing scope is an operator or method with an <operation result> or a
value returning procedure with a <procedure result> without a <variable
name>.
is not clear. The NOTE after the sentence implies that "without a <variable
name>" applies to operators, methods and procedures.
The meaning can be made clearer by rewording as:
The <expression> in <return> or <return area> shall not be omitted if the
enclosing scope is any of the following:
a) an operator with an <operation result> without a <variable name>;
b) a method with an <operation result> without a <variable name>;
c) a value returning procedure with a <procedure result> without a <variable
name>.
