   Just a little nit.

   I think he got the data types reversed.  First case A OF B is data item modifying the number of TIMES to PERFORM.  Second case A OF B is paragraph name.

Yes, indeed, the 1st one is the data item name and 
the 2nd one is the procedure (paragraph) name.

It does not change the issue with parsers, though.
