It is quite difficult to follow this kind of reports, because you do not
state how you tokenize, nor do you give tell what kind of syntax error you
get.

But here you have defined an item to be both NAME and INTEGER, so I gather
that the lines
>VALUE = 1
>Another = REAL
will be read as "VALUE =" followed by the list (according to your grammar)
"1 Another".

So somehow you will have to improve your grammar. Alternatives are one or
more of: Terminate list by a punctuation mark; separate list items by a
punctuation mark; enclose lists in some kind of brackets; restrict the
items of the list so that they do not clash with subsequently read items.
