I hope to not further trouble the waters of what is clearly a "don't do 
that, because it has no meaning" transgression of the (C) language 
definition, but isn't this a VMSious problem ?

I.e., getting 0 if you dereference a NULL pointer ?

It's been 20 years (5.4ish) since I last used VMS, but this is what came 
up to my mind when I saw this question ...

Cheers,
