Re: [Flashforth-devel] For-next loops - the New Design

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

No I do not insist.

Something like this should actually fullfill a 0 based index for-next 
that loops N times.

(FOR2):
cp0   [W14]
bra   nz, (FOR)
decf  [W14], [W14]
(FOR):
mov   [w14--], [w15++]
LABEL:

(NEXT):
decf  [--w15], [w15++]
bra   c, LABEL

Still there is the problem of renaming FOR to ?FOR that would break 
existing user code.
So I will call it FOR2.
I think that is reasonable because most words will never need to loop 
65536 times anyway.
