My experience is that you need to have something running
at the earliest possible stage, and make sure the code
is runnable through the entire project.

I would, like others, suggest that we start with a Linux (or *BSD)
system. The first major goals should be (IMHO) to provide a
subset of DCL *and* a Files-11/ODS-2 file system. To achieve this,
I think we should set some minor goals, including subsets of
LIB$, STR$ and a "proxy-SYS$" (as perhaps a wrapper around the
Linux system calls).

The next major goal would be to provide a linker and a program loader
which conforms more closely to the VMS calling standard. Several
other libraries need to be written here (LBR$, ..)

To sum it up, I would suggest that we start with something that we
have and which is running now. Then add the bare necessities,
and then exchange the system services.
