398 #############################################################################
400 eg. 'Script Solve_rat_equation' calls 'SubProblem (RatEq',..'
401 which would not allow to 'solve (y'' = -M_b / EI, M_b)' by this script
402 because Biegelinie.thy is subthy of RatEq.thy and thus Biegelinie.M_b
403 is unknown in RatEq.thy and M_b cannot be parsed into the scripts guard
406 Preliminary solution:
407 # the thy in 'SubProblem (thy', pbl, arglist)' is not taken automatically,
408 # instead the 'maxthy (rootthy pt) thy' is taken for each subpbl
409 # however, a thy specified by the user in the rootpbl may lead to
410 errors in far-off subpbls (which are not yet reported properly !!!)
411 and interactively specifiying thys in subpbl is not very relevant.
413 Other solutions possible:
414 # always parse and type-check with Thy_Info.get_theory "Isac"
415 (rejected tue to the vague idea eg. to re-use equations for R in C etc.)
416 # regard the subthy-relation in specifying thys of subpbls
