BSS   -  Block Started by Symbol, to reserve a block of un-initialized memory,
                    with the label assigned to the first word.

BES   -  Block Ended by Symbol, to assign the label to the last word of the
                     block.

             These were common to assemblers for early IBM machines, ie 1620,
             1130, 709/7090/7094  late 50's early 60's
