[Coco] C interpreter for Coco BASIC?

[go4retro at go4retro.com]

   The code can be 100% compatible, but compatibility is a tricky thing to
   define. The first step is geting the parser to understand the tokens
   and their parms, and the second is actually executing the
   functionality.
   For CocoFEST, I am hoping to get PRINT, GOTO, GOSUB, FOR, NEXT, END,
   STOP, and maybe a few others working completely (parsed and executed).
   For the rest, I will try to get the code to at least parse the
   keywords, but probably not execute.
   There's no reason why the code can't be improved after the show. For
   reasons that will become evident after the show, things like POKE,
   PEEK, INPUT, GET, OPEN, CLOSE operations can't be supported in my
   project, but I will try to put the code in to parse them and put stubs
   in so that others can implement them if desired.

   at some point, I need to settle on a CoCo project, focus on it, and see
   it through completion instead of just throwing out ideas / jumping from
   idea to idea.
