Have you considered converting them directly to C? I have significant
experience of BBC BASIC and, with the exception of string handling, I would
not normally expect this to be a major problem. A 3rd party library would
simplify the strings aspect - an alternative would be to use C-ish C++ and
std::string.

I am sure there are many who would be willing to help if you were to ask
about this specifically. comp.compilers is probably the most appropriate
newsgroup.
