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