(does anybody know why | there seem to be four(!) different magic numbers for 68000-family | executables?). +--------------- Portability, I guess. The magic numbers are the original PDP-11 ones. AMAGIC The standard magic number NMAGIC Shared text IMAGIC Separate I&D OMAGIC Overlay While all 4 are described as possible b.out structures in Xenix {2.3a,3.0} and Plexus sys3, other files say that only AMAGIC and NMAGIC are supported in the kernel. (b.out is what Xenix calls the standard 68000 object file, as opposed to a.out (PDP-11, Z8000) or x.out (Xenix common format). Plexus calls it bhdr.) -- Lord Charteris (thurb) ncoast!allbery@Case.CSNet (ncoast!allbery%Case.CSNet@CSNet-Relay.ARPA) ..decvax!cwruecmp!ncoast!allbery (..ncoast!tdi2!root for business) 6615 Center St., Mentor, OH 44060 (I moved) --Phone: +01 216 974 9210 CIS 74106,1032 -- MCI MAIL BALLBERY (WARNING: I am only a part-time denizen...)
