        Data types: B(bit), I, F, D(double), H(hollerith 4 char)
 
        Fixed length Database Header.  See titles_dbhdr.html.

        Although all entries except for the first one are defined as floats, those 
        beyond (and including) word 18 are type-casted as doubles when
        this bank is loaded in inmain.for in SNOMAN.
