However, since a 'C'-sourced debugger doesn't exist
That is not just baloney, that is fried baloney.

I sit here with 2 SILabs chips and one Philips chip talking to each other and one mouseclick brings me fron vieving and inserting breakpoints in the C source running on either.

There is no way in hades a "'C'-sourced debugger" as you refer to in other posts ("disassembling") can be made. The above, of course, refer to debugging where the debugging software link to the C source.
