2 elements of calculations.
3 they are partially held in association lists as ref's for
4 switching language levels (meta-string, object-values).
5 in order to keep these ref's during re-evaluation of code,
6 they are defined here at the beginning of the code.

190 # How to manage theorys in subproblems wrt. the requirement, #
191 # that scripts should be re-usable ? #
192 #############################################################################
194 eg. 'Script Solve_rat_equation' calls 'SubProblem (RatEq',..'
195 which would not allow to 'solve (y'' = -M_b / EI, M_b)' by this script
196 because Biegelinie.thy is subthy of RatEq.thy and thus Biegelinie.M_b
197 is unknown in RatEq.thy and M_b cannot be parsed into the scripts guard
200 Preliminary solution:
201 # the thy in 'SubProblem (thy', pbl, arglist)' is not taken automatically,
202 # instead the 'maxthy (rootthy pt) thy' is taken for each subpbl
203 # however, a thy specified by the user in the rootpbl may lead to
204 errors in far-off subpbls (which are not yet reported properly !!!)
205 and interactively specifiying thys in subpbl is not very relevant.
207 Other solutions possible:
208 # always parse and type-check with Thy_Info_get_theory "Isac"
209 (rejected due to the vague idea eg. to re-use equations for R in C etc.)
