Two of the boards are now operational. pic18f2620 and pic24hj128 There may be occasional droputs of the connectivity because the terminal server is behind a WLAN and the WLAN drops out once in a while. Mike |

I use the double dot as well to clear the stack an noticed the side
effect immediately.
I will fix it as soon as I have some time.
Period is simple as punctuation since it is already used as double flag.
I just want a simple scheme as possible. I have no intention to
sugarcote the interpreter with mathematical or bussiness symbols.
FlashForth is used mostly for HW control and bit-banging.
I have no plans to introduce floating point in FlashForth, so that
confusion will not arise anytime soon :-)

That side effect would be mildly annoying to this old bear since I routinely use a double-dot to purge the parameter stack when experimenting... Might be tolerable if the "sp!" was made available and I could actually get a stack-purge word to not restart the interpreter (grin).
Save periods for floating point, they're confusing enough as "double flags" to the novices I try to introduce to the system. I still believe there's a reason we call them "Decimal Points".

Hello Mikael, Thanks for the realization of punctuation. I have tested it, and works well. I see only one side-effect. Two or more dot without any real number digit generates doube zero: .. -> 0 0 ... -> 0 0 I think, it would be better to see them as words, if it is not too difficult to realize. BR Attila |

Fellows,
Here is a revised reference sheet for FF5.
http://dropbox.eait.uq.edu.au/e4pjacob/flash-forth/flash-forth-5-sheet-2014-05-16.pdf
Let me know if I should fix anything, but I'm hoping that it's pretty
close to being done for now.
Cheers,
Peter J.

Hi, I have been quite busy lately with other things. Summer is coming, so I don't have that much time to sit inside at the computer. If you look at the code below, both if statements are equally fast in FlashForth since the 0= will be optimized away by the compiler. 4 5 bit?: testbit testbit if blabla then testbit 0= if blabla then BR Mike On 05/13/2014 09:44 PM, Herman Attila wrote: > Hi Mikael > > - Previously we talk on the punctuation of numbers, but I can't found > it in FF5.0. > The latest version of idea that you wrote (27. march): > > ------------------------------------------------ > I plan now to do it like this > Just one punctuation char for grouping digits. > > Single precision number > #-10.345 > %1011.1101.1111.0000 > $fad.e > > Double precision numbers > %1011.1101.1111.0000. > #-10.345. > $fade.babe. > ------------------------------------------------- > > Other: > > - I know, it is a bit late, but I have some thought on the bit > manipulating words.

Hi Mikael - Previously we talk on the punctuation of numbers, but I can't found it in FF5.0. The latest version of idea that you wrote (27. march): ------------------------------------------------ I plan now to do it like this Just one punctuation char for grouping digits. Single precision number #-10.345 %1011.1101.1111.0000 $fad.e Double precision numbers %1011.1101.1111.0000. #-10.345. $fade.babe. ------------------------------------------------- Other: - I know, it is a bit late, but I have some thought on the bit manipulating words. The incidence of testing for bit=0 and bit=1 are similar. Using a bit0?: word would be faster then inverting result of bit? . Maybe the notation is bit0?: and bit1?: for the symmetry. I think, a bit toggle word (perhaps bit-tgl: ) would be a good addition to bit0: and bit1: BR Attila |

Thanks Pete. Your rewrite is better.

Thomas,
There's an example of using the bit set and bit clear assembler
words in section 12.1 of the tutorial guide.Here's the most recent version.

Yepp, that needs to be fixed. I am not updating older FF versions, only 5.0 and later will be updated.

Simon,
The documentation comments in the assembler source agree with you.
; NUMBER? c-addr -- n 1
; -- dl dh 2
; -- c-addr 0 if convert error
dw L_TONUMBER
L_NUMBERQ:
db NFA|7,"number?"
The fix also needs to be made to the most recent wordsAll.txt (line
695), I believe.

Hello,
I think I've noticed an error in this file where
---------------
number? ( c-addr -- n/d/c-addr flag )
Convert string to number
# is decimal prefix
$ is hexadecimal prefix
% is binary prefix
Flag: 0=error, 1=double, 2=single
---------------
I've been testing this with single and double and the flag
I think should be 1=single, 2=double.
Is this right?
Thanks,
Simon.
