Where can I find version 4.9.
I only have 4.7.
Thanks for your patience and help.
Greetings Armando

I've updated the files on my web site

I finished and saved the snake program with Autosave
taken from the Forth c64 version.
I can't find a program to write Seq files.
With what program did you write the Demo.fs files. ??
I only have programs for Vic20 and c64 that read and print Seq files but don't write them.
Attached is the Snake. file
Load "snake.prg",8,1 : Sys8192
Thanks for help. Armando

Very colourful.

I don't edit files actually on the VIC, I prefer use an editor on my desktop PC and copy them into a disk image. I use my own tools (cbmshell) but you can also do this with the c1541 program which comes with VICE.

There are probably text editors on the VIC you could use, I don't know of any myself.

HI,
I insert two listings that I made.
One normal and the other for Minigrafik.
I would like to have them in Vforth if possible.
They both work but the execution speed is very slow, especially for the version with minigrafik.
I am sure that with the Vforth they will be faster.
Thank you . Greetings Armando

This is an unfair and misleading comparison! The version in pure BASIC only works on the text screen, whereas the MG version sets pixels in the graphics screen and correspondingly has to operate on 64 hires pixels instead of 1 single character cell for a given screen estate.

Here is how I would implement those Automatons with MINIGRAFIK. The first line are random pixels, subsequent lines have Rule 110 applied (can be changed with the values in line 9):
The program above needs roughly 10 1/2 minutes to fill the screen. It avoids the slow 2^A operation followed by AND N to mask out the relevant rule bit, and instead does a direct lookup in the array C(L,M,R) filled in line 2 from the data in line 9 (the 8 digits represent the rule number in binary, %01101110 = 110 decimal). Lines 4 and 6 also handle the wrap-around at the left and right edge.

Forth could do all relevant calculations with byte and word values. That surely is faster than the (implied) float arithmetic of BASIC. Nothing to prove here.

My graphics vocabularies don't currently have a word to test if a pixel is set, I'll add one and then post a FORTH implementation.

I've been recently trying to implement an efficient Game of Life, but even with optimizations it's very slow.

Thank you.
if you can, the low resolution version (Basic) converted to Vforth is also fine.
I would like.

Here's the equivalent of the BASIC (text mode) version in FORTH

HI,
thanks for help. I try to do it.

HI,
Here is the Automata .Prg file.
Version with Vforth.
Very beautiful and fast.
Load with Load "automata* ",8,1 : then Sys 8192.
Thanks to the author (Srowe) for the cooperation.

I'd nearly forgotten about this. I've added a new example to the latest release which contains 3 versions: text, low resolution and high resolution graphics.
