        The methods associated to LIRSOSO are

       SOS_IDEN  SOS_ITYP  SOS_SOLI  SOS_FRAC

       SOS_IDEN   Input the content of IDEN index,the identification
                 number of new  solid-solution.
                 call: OBJ1%SOS_IDEN  ENTI1 ;

       SOS_ITYP Input the content of ITYP index. Integer, type of
                solid-solution
                          3  precipitated solid-solutions which are not
                             allowed to dissolve.
                          4  species with fixed activity
                          5  dissolved solid-solutions which are subject to
                             to precipitation
                          6  species which are not to be considered
                             at all.
                    For type 3 and 4, mole fractions must be stated, but
                    not for type 5 and 6.
                 call: OBJ1%SOS_ITYP  ENTI1 ;

       SOS_SOLI Input the content of SOLID index. LISTENTI type object
                which contains the identification numbers of pure 
                endmembers of the solid-solution (<36).These endmembers
                will set to type 6 (they are used during the
                calculation, but have no physical existence).
                 call: OBJ1%SOS_SOLI  LENTI1 ;

       SOS_FRAC Input the content of FRACTIO index. A LISTREEL type
               object which contains the mole fractions of every 
               endmember. (If the solid-solution is set to type 3 or 4,
               operator chi1 needs mole fractions for the calculation
               of solid-solution stoichiometric coefficients and logK.
               If the solid-solution is set to type 5 or 6, operator
               chi2 is able to calcul mole fractions, stoichiometric
               coefficient and logK.
                 call: OBJ1%SOS_FRAC LREEL1 ;
