I have now added a working SEE word to the disassembler, to enable the user to disassemble whole words, both compiled from Forth source code and built into the zeptoforth kernel. There are still a few kernel words that include instructions not decoded by the disassembler, but these are very few. I will soon produce a new release including the disassembler. Considering the size of the flash on the MCU's I am targeting, it does not make sense to make separate binaries with and without the disassembler, particularly with how padding out flash for the purposes of implementing CORNERSTONE works on the STM32F407 (which currently results in significant quantities of wasted flash space that could be taken up, in part, by the disassembler).
