 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 can understand that but that is not interesting. But the question whether it is easier to use neos as universal compiler than a web browser is interesting. A web browser
certainly can compile any programming language that can be
compiled if it is given a script (HTML+javascript) that
defines the source and target languages.

Yes, but does it halt?

If it does not deliver the object file in reasonable time the script is bad.
