I am trying out apout using the "1972_stuff" binaries. When using "as" to assemble "ux" (e10-01 through e10-02) it gives an error "m 0024" (multiply-defined label) for the line: mount: .=.+1024. I assume this is because the assembler has predefined the "mount" system call (I ran across this earlier when using my system call table sys.s with ux with the v7 assembler). We can work around this (ie. use the v7 assembler without the definition for "mount"), but it worries me a little -- why does the listing have such an obvious and large flaw? The symbol "mount" is used in several places, so this isn't likely to be a small typo. I can't think of a good explanation as to why this error would exist in the listing other than possibly pointing to another assembler being used. Tim Newsham http://www.thenewsh.com/~newsham/
