    24 We stepwise build \ttfamily Inverse\_Z\_Transform.thy \normalfont as an

    25   exercise. Because subsection~\ref{sec:stepcheck} requires

    26   \ttfamily Inverse\_Z\_Transform.thy \normalfont as a subtheory of \ttfamily

    27   Isac.thy\normalfont, the setup has been changed from \ttfamily theory

    28   Inverse\_Z\_Transform imports Isac \normalfont to the above one.

    31   \textbf{ATTENTION WITH NAMES OF IDENTIFIERS WHEN GOING INTO INTERNALS}

    32   \end{center}

    33   Here in this theory there are the internal names twice, for instance we have

    34   \ttfamily (Thm.derivation\_name \isa{rule{\isadigit{1}}} =

    35   "Build\_Inverse\_Z\_Transform.rule1") = true; \normalfont

    36   but actually in us will be \ttfamily Inverse\_Z\_Transform.rule1 \normalfont%
