What subset of VMS data types are supported by C ?

You've been listening to Steve too much.

Anything can be improved.  However, descriptors, as a concept, are a 
whole bunch better than not having descriptors, or something better.

Hey, I'm not the compiler guy.  Seems that you might be.  Are you 
mentioning your failings?

Yeah, I remember "real" documentation, and, I still have some of that.
