I see.   In other words the assembler cannot produce MMO, but the linker can.

     have to ask - do you know what these formats are (as opposed to
     e.g. trying to see what object formats can be produced)?
     Knowing what you try to achieve might help improving the
     answers.

No.  I am experimenting, in order to become (more) familiar with binutils.
     
     It's admittedly a bit unclear in the ld documentation that
     "emulation" can mean "output format" (one might be tempted to
     use "-b", but that'd be wrong), but I think the rest of the
     information you seek is there.  I really much prefer improving
     the linker documentation over clarifying it on a mailing list,
     so please have a look and tell the first question that comes to
     mind.
     
I was a little surprised to find that the default output filename from the 
assembler was "a.out", since I am used to that being an executable file.
I was then  initially confused, when I tried passing that file to the linker
and got the error:

./ld/ld-new -m mmo a.out
a.out: file not recognized: File truncated

until I realised that it was overwriting the input file with its output.

Why does the assembler produce a file which cannot be passed to the linker
without renaming?
