   For the OS/360 object files, I don't believe there is anything   
   that the assembler can't produce, but with LE and GOFF, there are   
   some things.  I don't remember them, and a web search doesn't   
   show them.   
      
   Well, the assemblers have PUNCH which lets you write any bits   
   you want into the object file.  That is sometimes used to generate   
   linker control cards into the object deck, and also to generate   
   the SYSGEN files, which all come from the assembler.
