  FYI Collective Info,

    1)  CRAY YMP work (many 12 yrs ago) was done on Haldane repets (using
  USN Tables), published in open literature, and adopted by NAUI AS SUCH --
  has nothing to do with RGBM nor codes;

    2) SAME thing about SGI ORIGIN risk analysis performed on rec repets
       using Haldane and phase risk indicators -- nothing to do with RGBM
       nor codes used for staging.

    3) recall that I work in a TOP SECRET side of LANL;

   Cheers,

   BW
