We want XMAGIC to aid debugging of locally-written programs. I don't have the time to fix all of the poorly-written utilities that try to reference through zero. By continuing to use ZMAGIC as the default I can sidestep the issue to some extent. Of course, any library routines which expect references through (foo *)0 to work will need to be modified. Does anyone have a feel for the number of routines that may need modification? -- John Bruner (S-1 Project, Lawrence Livermore National Laboratory) MILNET: jdb@mordor.ARPA [jdb@s1-c] (415) 422-0758 UUCP: ...!ucbvax!dual!mordor!jdb ...!decvax!decwrl!mordor!jdb
