SUBROUTINE setsd(iseed1,iseed2)
C**********************************************************************
C
C SUBROUTINE SETSD(ISEED1,ISEED2)
C SET S-ee-D of current generator
C
C Resets the initial seed of the current generator to ISEED1 and
C ISEED2. The seeds of the other generators remain unchanged.
