<P>
If in doubt about the amount of
workspace to supply to a ScaLAPACK
routine, the user may choose to
supply <I>LWORK</I>=-1<A NAME="3494"> </A>
and use the returned value in
<I>WORK</I>(1) as the correct value
for <I>LWORK</I>. Setting <I>LWORK</I>=-1
does not invoke an error message
from <TT>PXERBLA</TT> and is defined
as a global query<A NAME="3496"> </A><A NAME="3497"> </A><A NAME="3498"> </A>.
