 \saNote{}
 The \wcpMod{} doesn't have a ``$\resHi$'' column.
-For that module we omit $\stackItemValHi{4}$ from the source and ``$\resHi$'' from the target.
-Recall from section~(\ref{hub: instruction handling: stateless: wcp high part is zero}) that for \wcpMod{}-instructions we impose the vanishing of the ``result's'' high part.
+For that module we change ``$\resHi$'' from the target to 0 to ensure the high paty of the result is 0.
