This routine sets the parameters defining the preconditioner. More
precisely, the parameter identified by <code>what</code> is assigned the value
contained in <code>val</code>. The routine may also be invoked as a method
of the preconditioner object; in this case it is also possible to
specify an optional <code>ilev</code> argument that restricts the effect of
contained in <code>val</code>.
<P>
The routine may also be invoked as a method
of the preconditioner object as in the following:
<DIV ALIGN="CENTER">
<code>call p%set(what,val,info [,ilev])</code>
<BR>
</DIV>
In this case it is also possible to specify an optional <code>ilev</code>
argument that restricts the effect of
the call to the specified level.
The alternative forms of this routine are designed to allow
extensions of the library.
<P>
Finally, if the user has developed a new type of smoother and/or
solver by extending one of the base MLD2P4 types, and has declared a
variable of the new type in the main program, it is possible to pass
the new smoother/solver variable to the setup routine as follows:
<DIV ALIGN="CENTER">
<code>call p%set(smoother,info [,ilev])</code>
<BR><code>call p%set(solver,info [,ilev])</code>
</DIV>
In this way, the variable will act as a <I>mold</I> to which the
preconditioner will conform, even though the MLD2P4 library is not
modified, and thus has no direct knowledge about the new type.
