Ok.

Yes, but I am not sure this is documented.  Calling decc$main should make it.

I haven't tested http.  I use ftp.  I think that zip should work too (for .obj).

I haven't tested sftp.  Note that only transferring .obj is difficult, .exe and text files work well 
(according to my experience).

Here we are only interested in alpha64-dec-vms, which is more difficult due to pointer size.
But you need copying for argv[] because it's an array of pointer.
