Response most appreciated .
On second question - I was wondering if there was an overview of how the
flashforth or any forth system is" put together . I still
have my Brodie Book from way back when" but was looking for an explanation
of the program flow - :
eg On startup the assembler code sets up the pointers to the stack in
routine ....... and initializes the serial port in routine ..... .
Thereafter
the system stays in a loop waiting for character from the serial port and
on seeing a space call routine .......
that looks up the word in the dictionary in routine ......
and so on .
Many years Hendrix wrote a manual on how the small C compiler worked and I
was looking for something similar
