For the development phase I would like to have a real
interpreting ascii source.
For flight the number & size of telecommands is limited, therefore it
would be nice to have bytecodes
with a bytecode compiler/decompiler to be used on ground. That's
thinking about FCode.
FCode isn't full-featured Forth though, it's more like a
scripting-language subset. In particular, it doesn't
have DOES> . FCode isn't much smaller than (compressed)
source text either, btw.
