I am trying to implement the words mentioned in section 220.127.116.11 of open firmware
specification viz. cpeek, wpeek etc.
For this I have already implemented exception handling, which is in C and assembly.
Sounds interesting. Did you have a look at the exception handling code I
checked in a while ago?
Now to implement these words I need to create some
flags (variables) which can be accessed from both forth and C.
Is there any way by which I can access the same variable from both c and forth.
Yes, look at the handling of "last". Variables in forth are just normal
words that push the address of the memory associated with them to the
stack. You can use this with the normal forth-c-bindings
If you publish a patch of your work people here can likely help you.
