Re: [Flashforth-devel] jumping without a return

[Mikael N. <mik...@fl...>]

I am not sure what you are after, but the Forth way is to use EXECUTE.
If you give an address to EXECUTE
on the parameter stack, the code execution will continue at that
address. 

12 ok<$,ram> 12 
2+ ok<$,ram> 14 
' 2+ ok<$,ram> 14 15b8 
execute ok<$,ram> 16 

Any other solution must revert to ATmega assembler to compile a jmp or
ijmp. 

In order to not break the Forth there must by a return address on the
stack. That gets you back to after the address where EXECUTE was
executed. 

What do you want to achieve ?

Kind of like you would with a tail call recursion, but in any arbitrary place? It looks like there are some jumping instructions in ff5 reference but I don't understand how to use them. I'm thinking in avr context if that makes a difference.
