How do you do that? You mean by things in A and B?

What kind of rewrite?

Printf and scanf doesn't use descriptors in VMS either.

Eventually, lib$get_output and lib$put_output will be used; both routines
can probably be implemented by using read and write on stdin and stdout.
In VMS both use RMS $get and $put, but FreeVMS as of now does not
have VMS terminal drivers or support process logicals (sys$output).

Doesn't C on VMS expect null termination, too?
I hope you don't expect us to write a C compiler?
(I am not quite sure how to interpret that smiley)
