248 # How to manage theorys in subproblems wrt. the requirement, #
249 # that scripts should be re-usable ? #
250 #############################################################################
252 eg. 'Script Solve_rat_equation' calls 'SubProblem (RatEq',..'
253 which would not allow to 'solve (y'' = -M_b / EI, M_b)' by this script
254 because Biegelinie.thy is subthy of RatEq.thy and thus Biegelinie.M_b
255 is unknown in RatEq.thy and M_b cannot be parsed into the scripts guard
258 Preliminary solution:
259 # the thy in 'SubProblem (thy', pbl, arglist)' is not taken automatically,
260 # instead the 'maxthy (rootthy pt) thy' is taken for each subpbl
261 # however, a thy specified by the user in the rootpbl may lead to
262 errors in far-off subpbls (which are not yet reported properly !!!)
263 and interactively specifiying thys in subpbl is not very relevant.
265 Other solutions possible:
266 # always parse and type-check with Thy_Info_get_theory "Isac"
267 (rejected due to the vague idea eg. to re-use equations for R in C etc.)
