AB  - We report on our latest results in the calculation of the two–mass contributions to 3–loop operator matrix elements (OMEs).  These OMEs are needed to compute the corresponding contributions to the deep-inealstic scattering structure functions and to generalize the variable flavor number scheme by including both charm and bottom quarks.  We present the results for the non-singlet and A<sub>gq,Q</sub> OMEs,  and  compare  the  size  of  their  contribution  relative  to  the  single  mass  case. Results for the gluonic OME A<sub>gg,Q</sub> are given in the physical case, going beyond those presentedin a previous publication where scalar diagrams were computed.  We also discuss our recently published two–mass contribution to the pure singlet OME, and present an alternative method of calculating the corresponding diagrams.
