hey Gopal
me has downloaded the sources from the cvs.. but pnet does not compile anymore... says some undefined references: ILGenericParCreate, ILGenericParSetName, ILGenericParSetKind .. etc. and the linker ld aborts... i managed to compile treecc.. but .. the error sounds as when some libraries were missing.. sorry for disturbing u with compile stuff.. but i hoped that i might find a solution to the following problem: the "System" assembly is not found by reflection... see attachment... and another thing: when the first line (using bla bla..) is commented out.. cscc comes up with an error message though it shouldnt..
(with the official 0.5.2 release)

.. wanna grap the newest sources but cant ping at the moment.. is it just me???

Most likely , your firewalls might be blocking CVS access. In that case
you might want to look at port 443 CVS access in subversions ;-)

Or if your institution is HTTP proxied (like mine) , you might want to get it off the Savannah backups section for an unofficial CVS snapshot.

.. mhh.. but how do i know which Null is the one of the StreamReader class?? is it the one of type StreamReader or the one of type

I can't test it in .NET , so I can't say for sure . Anyway mono won't run it and mint gives exactly the same answer.

TextReader.. most probabely of StreamReader but how can i be sure, ie. how can my compiler (oberon) be sure?

What I'm asking is that -- are you getting different results with MS.NET ?
I think the problem could be fixed relatively easily , if I knew what it
actually needs.

My question is reflected by the attached code.

Btw, the compiler should not have to worry too much ... as this is a static field. StreamReader.Null and TextReader.Null should give the right class to pick ..

i'd say yes.. - if not shadowed..

They are not shadowed (aka overriden) as both are of different types.
I don't think I could put those in the same slots ?.
