 If a native FORTRAN IV compiler can parse it then neos can parse it as
long as it is somehow expressable in the neos attribute grammar.

 If you don't know how to express it in the neos attribute grammar then
nobody knows and neos is not universal, at lieast in the practical
sense.

  You don't understand, Mikko. You probably think that "neos can parse it"
means that neos can parse it. What it really means is that /in Mr
Flibble's head/ neos can parse it, and anything in Mr Flibble's head is
right by definition, and /therefore/ neos can parse FORTRAN IV even if
it can't.

 I see no reason why neos can't parse FORTRAN IV, FACT.

I can see a reason why it can't be used for that purpose: you have not
told how it can be done. If you can't tell how to use neos then nobody
is going to use it. If you can't solve the small problem of tokenizing
the example lines
        REALITY IS, AS I MAY
        LOGICALLY SAY, REAL
        LOGICAL = WHAT I SAY
then nobody will try the bigger problem of tokenizing all of FORTRAN IV
or any later Fortran and parsing and compiling it.
It does not really matter what can be done if nobody is going to try.
