This prefix is particularly useful for nested use of <A HREF="../SLES/SLES.html#SLES">SLES</A>. For
example, the block Jacobi and block diagonal preconditioners use
the prefix "sub" for options relating to the individual blocks.
<P>
On the fortran side, the user should pass in a string 'prifix' of
sufficient length to hold the prefix.
