\begin{isamarkuptext}%

We stepwise build Inverse_Z_Transform.thy as an exercise.

  Because subsection "Stepwise Check the Program" requires Inverse_Z_Transform.thy 

  as a subtheory of Isac.thy, the setup has been changed from

  "theory Inverse_Z_Transform imports Isac begin.." to the above.

  ATTENTION WITH NAMES OF IDENTIFIERS WHEN GOING INTO INTERNALS:

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

  (Thm.derivation_name \isa{rule{\isadigit{1}}} = "Build_Inverse_Z_Transform.rule1") = true;

  but actually in us will be "Inverse_Z_Transform.rule1"%
