关于BSS看大师是怎么说的:

bss = "Block Started by Symbol"        
        Dennis Ritchie says:
            Actually the acronym (in the sense we took it up; it may
            have other credible etymologies) is "Block Started by
            Symbol." It was a pseudo-op in FAP (Fortran Assembly [-er?]
            Program), an assembler for the IBM 704-709-7090-7094
            machines.  It defined its label and set aside space for a
            given number of words.  There was another pseudo-op, BES,
            "Block Ended by Symbol" that did the same except that the
            label was defined by the last assigned word + 1.  (On these
            machines Fortran arrays were stored backwards in storage
            and were 1-origin.)
            The usage is reasonably appropriate, because just as with
            standard Unix loaders, the space assigned didn't have to be
            punched literally into the object deck but was represented
            by a count somewhere.


是哪位总统接见Dennis Ritchie,并给他骑士勋章,因为他发明了C
