C***PURPOSE  Solves the COMPLEX SYMMETRIC SYSTEM  A*X=B  using factors
C            from CSIFA.
C***DESCRIPTION
C
C     CSISL solves the complex symmetric system
C     A * X = B
C     using the factors computed by CSIFA.
C
C     On Entry
C
C        A       COMPLEX(LDA,N)
C                the output from CSIFA.
C
C        LDA     INTEGER
C                the leading dimension of the array  A .
C
C        N       INTEGER
C                the order of the matrix  A .
C
C        KVPT    INTEGER(N)
C                the pivot vector from CSIFA.
C
C        B       COMPLEX(N)
C                the right hand side vector.
C
C     On Return
C
C        B       the solution vector  X .
C
C     Error Condition
C
C        A division by zero may occur if  CSICO  has set RCOND .EQ. 0.0
C        or  CSIFA  has set INFO .NE. 0  .
C
C     To compute  INVERSE(A) * C  where  C  is a matrix
C     with  P  columns
C           CALL CSIFA(A,LDA,N,KVPT,INFO)
C           If (INFO .NE. 0) GO TO ...
C           DO 10 J = 1, P
