I was using BBCBASIC(86) on PC's way past it's sell by date and I ended 
up storing all the source files as text in subversion and then 
converting them into tokenised versions to actually run them. As part of 
this I also added the ability to include another file, so that you could 
have a library of routines shared between modules (we used a version 
that was limited to 64k of program and 64k of data). I don't know if 
it's in use today, but I think it was still running when Vista came out.

We were kinda stuck with the way it worked, as we didn't have control 
over BBCBASIC(86). But as you do then I'd recommend loading and editing 
the basic program as text, then when you type RUN then push the code 
through something like lvvm to give you native code.

Also put in place something that can load and save native code modules, 
so that you don't have to even have the source file. Oh and replace line 
numbers with labels.
