CISION array, dimension (LDDC,MV)
          If JOBD = 'D', the leading PZ-by-MV part of this array
          contains the direct input/output transmission matrix Dc
          of the closed-loop system.
          The array DC is not referenced if JOBD = 'Z'.

  LDDC    INTEGER
          The leading dimension of array DC.
          LDDC &gt;= MAX(1,PZ) if JOBD = 'D'.
          LDDC &gt;= 1 if JOBD = 'Z'.
