jan@42381: First we transfer both, knowledge and tests into:

jan@42381:   in order to immediately have the test results.
jan@42381: 
jan@42381:   We copy \ttfamily factors\_from\_solution, drop\_questionmarks,\\
jan@42381:   ansatz\_2nd\_order \normalfont and rule-sets --- no problem.
jan@42381:   
jan@42381:   Also \ttfamily store\_pbt ..\\ "pbl\_simp\_rat\_partfrac"
jan@42381:   \normalfont is easy.
jan@42381: 
jan@42381:   But then we copy from:\\
jan@42381:   (1) \ttfamily Build\_Inverse\_Z\_Transform.thy store\_met\ldots "met\_SP\_Ztrans\_inv"

jan@42381:   (2) \ttfamily Partial\_Fractions.thy store\_met\ldots "met\_SP\_Ztrans\_inv" 
jan@42381:   \normalfont\\ and cut out the respective part from the program. First we ensure that
jan@42381:   the string is correct. When we insert the string into (2)
jan@42381:   \ttfamily store\_met .. "met\_partial\_fraction" \normalfont --- and get an error.%

jan@42381: \begin{isamarkuptext}%
jan@42381: At the present state writing programs in {\sisac} is particularly cumbersome.
jan@42381:   So we give hints how to cope with the many obstacles. Below we describe the
jan@42381:   steps we did in making (2) run.
jan@42381:   
jan@42381:   \begin{enumerate}
jan@42381:     \item We check if the \textbf{string} containing the program is correct.
jan@42381:     \item We check if the \textbf{types in the program} are correct.
jan@42381:       For this purpose we start start with the first and last lines
jan@42381:      \begin{verbatim}
jan@42381:      "PartFracScript (f_f::real) (v_v::real) =       " ^
jan@42381:      " (let X = Take f_f;                            " ^
jan@42381:      "      pbz = ((Substitute []) X)                " ^
jan@42381:      "  in pbz)"
jan@42381:      \end{verbatim}
jan@42381:        The last but one line helps not to bother with ';'.
jan@42381:      \item Then we add line by line. Already the first line causes the error. 
jan@42381:         So we investigate it by
jan@42381:       \begin{verbatim}
neuper@48761:       val ctxt = Proof_Context.init_global @ { theory } ;
jan@42381:       val SOME t = 
jan@42381:         parseNEW ctxt "(num_orig::real) = 
jan@42381:                           get_numerator(rhs f_f)";
jan@42381:       \end{verbatim}
jan@42381:         and see a type clash: \ttfamily rhs \normalfont from (1) requires type 
jan@42381:         \ttfamily bool \normalfont while (2) wants to have \ttfamily (f\_f::real).
jan@42381:         \normalfont Of course, we don't need \ttfamily rhs \normalfont anymore.
jan@42381:       \item Type-checking can be very tedious. One might even inspect the
jan@42381:         parse-tree of the program with {\sisac}'s specific debug tools:
jan@42381:       \begin{verbatim}
neuper@48790:       val {scr = Prog t,...} = 
jan@42381:         get_met ["simplification",
jan@42381:                  "of_rationals",
jan@42381:                  "to_partial_fraction"];
jan@42381:       atomty_thy @ { theory } t ;
jan@42381:       \end{verbatim}
jan@42381:       \item We check if the \textbf{semantics of the program} by stepwise evaluation
jan@42381:         of the program. Evaluation is done by the Lucas-Interpreter, which works
jan@42381:         using the knowledge in theory Isac; so we have to re-build Isac. And the
jan@42381:         test are performed simplest in a file which is loaded with Isac.
jan@42381:         See \ttfamily tests/../partial\_fractions.sml \normalfont.
