The reason I ask is that this word definition doesn't behave the way it should.

Code:

: EGGSIZE
        DUP  18 < IF  ." reject "      ELSE
        DUP  21 < IF  ." small "       ELSE
        DUP  24 < IF  ." medium "      ELSE
        DUP  27 < IF  ." large "       ELSE
        DUP  30 < IF  ." extra large " ELSE
                      ." error "
        THEN THEN THEN THEN THEN DROP ;

When I execute this word in gforth I get the following results:

Code:

eggsize reject  ok
eggsize small  ok
eggsize small  ok
eggsize small  ok
eggsize medium  ok
eggsize medium  ok
eggsize medium  ok
eggsize large  ok
eggsize large  ok
eggsize large  ok
eggsize extra large  ok
eggsize extra large  ok
eggsize extra large  ok
eggsize error  ok

In Tali Forth I get this result:

Code:

eggsize reject medium  ok
eggsize small  ok
eggsize small  ok
eggsize small  ok
eggsize small  ok
eggsize small  ok
eggsize small  ok
eggsize small  ok
eggsize small  ok
eggsize small  ok
eggsize small  ok
eggsize small  ok
eggsize small  ok
eggsize small  ok
eggsize small  ok

It seems to me that nested if statements are not that well supported.
So is Tali Forth still maintained?

I should mention that I used py65mon to run Tali Forth.

A reboot of the emulator and Tali Forth gave me this result:

Code:

eggsize reject  ok
eggsize  small  ok
eggsize small  ok
eggsize small  ok
eggsize medium  ok
eggsize medium  ok
eggsize medium  ok
eggsize large  ok
eggsize large  ok
eggsize large  ok
eggsize extra large ok
eggsize extra large ok
eggsize extra large ok
eggsize error  ok
eggsize error  ok

What's going on?

What happens when you try other Forths in your simulator (which is not, by the way, an emulator)?

Tali is alive, but she's been benched while I'm getting her big sister Liara for the 65816 (https://github.com/scotws/LiaraForth) up and running. Unfortunately, it might be a bit before I can take a look - I only have the emulator as well at the moment. With a bit of luck, I can at least confirm the problem later today, and then see what is going on.

Because you're using Tali (very honored, by the way), the near-term plan is to get Liara to about where Tali was in terms of functionality, and then go back and do a very major rewrite of Tali with what I've learned from Liara (split headers and code, etc). I'm aiming to have them echo each other so that in future, features can be added in parallel, with the same routine names etc. Though to be honest the idea of going back to the 65c02 after coding for the 65816 fills me with a certain sense of dread ...

Please let me know if you find out anything more about the bug!

Funny how that works, eh?

Sorry, I just tried to reproduce the error on py65mon from a cold start, immediately defining the new word, and it worked as it should. Do you remember what you were doing before the error occurred? Tali is not the most stable girl, a result of her creator trying to bee Too Clever By Half with some of the internal routines ... EVALUATE is especially horrible in retrospect, and that's where IF comes from during boot.

I think I entered the word several times because I managed to sausage finger the first and second (perhaps even a third) attempt entering it. When I eventually typed it in correctly it behaved as I described. But after a cold boot and entering the word correctly the first time everything worked fine. Don't take this as gospel though, because my memory is a bit hazy on the details.

Maybe someone with better trained Forth eyes than mine can spot what is happening.

Huh. I don't see anything obvious. Given that Tali in the current form tends is not the most robust when it comes to errors - Liara does this better already - I'm guessing something got mixed up internally at some point (duh, I know). I'll make a mental note that this happened, and if somebody has the same problem before I can get to rewriting Tali, we can see about tracking it down. Again, thanks for the info!

Cool.
The reason I'm so interested in Tali Forth is that I'm building a 65C02 SBC and I want Tali Forth to be the OS so to speak, if that makes any sense. So the SBC will have a VT100 terminal serial interface, so no graphics, just plain 80x24 text display (the project is called Micromite and the url is http://www.siliconchip.com.au/Issue/2014/July/Micromite%2C+Pt.3%3A+Build+An+ASCII+Video+Display+Terminal) and an IDE interface.
The inspiration for this project is an 80s computer called Jupiter ACE and I wanted to build something similar to that. Tali Forth is the first Forth I've come across that is 6502 based and platform independent and easily ported to an SBC.
Hence my interest in Tali Forth.
Tali needs some extras though like IO words so you can read, write files and directories. Store and load word definitions (not sure how to do that though, but this is early days in the project).

Have you tried typing (pasting) that initial transcript back in to see if you duplicated the bug? It's a great transcript, but it doesn't show the entire history of the session that actually had the bug.

I think it would be helpful to see if it replicates from the cold start of the image.

(I assume the "compiled" message are from Tali Forth...)

What were you planning to use for the IDE interface? If it's a raw block device, then implementing file support will be more difficult, as you have to implement a filesystem. But I'm pretty sure I've seen interfaces that let you interact with a DOS formatted flash cards using a high level serial protocol (SPI I think?). That, obviously, would be much easier. If you simply have the IDE drive as a block device, then initially you could just use the basic BLOCK I/O provided in early Forths.

I'm surprised you didn't find the original 6502 Fig Forth, but there's likely not a simple binary that "just works" in something like py65, and the raw assembly may not work with a modern assembler. It would be close, as it's pretty basic 6502 assembly. But out of the box, drag and drop, no. Plus it would have to be ported to something like py65 anyway (which isn't difficult, I ported mine readily -- not to py65, but my own).

It's at http://6502.org/source/forth65.zip .

It might be a good starting point for 6502 IDC Forth, but you'll want to improve it. Note that it has the UM/MOD division bug, and, and the UM* multiplication bug (the link here gives not only my fix, but others' efficiency improvements), and the D< comparison bug. Fixes are given at the links.

Also, though I'm obviously biased, remember that DO/LOOP is still the old, pre-ANSI version (they give different results), and is 6502, not 65C02.

Have you taken a peek at eForth's FOR AFT and NEXT Scot?
