In my opinion, such unnecessary complications cause frustration for beginners and can effectively discourage them from exploring the Kowalski Simulator. It's a shame, because it's actually a good program.

It seems you're experiencing some kind of outage that's been blocking access to www.6502.org from half of London, UK, since yesterday. Maybe the administrator should investigate

Garth has some good illustrations of that on his website. I don’t indent things such as loop bodies in my source, but if I did, I would be using a model such as his.
This is a good example, I advise you to try to assemble e.g. this MACRO using Kowalski Simulator. ;)
BEQlong: MACRO LBL
BNE bel1 ...

In my opinion, this example source code is more readable, and I can locate important fragments more quickly than

the next one. Especially if it's extensive.

Unfortunately, for the assembler in Kowalski Sym. the first one ...

Thanks for the fix. It seems to be working now.

I suggest ignoring at least the first tab character in labels. In my opinion, this would improve the readability of user-generated source code and reduce the number of frustrating errors.

Thanks for the help, I wrote this macro:
puta: .MACRO b
.a .=<* & $03
.IF .a==0
NOP
.ENDIF
.IF .a==2
NOP
NOP
NOP
.ENDIF
.IF .a==3
NOP
NOP
.ENDIF
.DB $DB,<.beta,>.beta
.RS b
.beta:
.ENDM
It may not be perfect, but it seems to meet my needs, and I learned something along the way.

Why ...

Thanks
I'm trying to write a macro that would allow me to ensure that 32-bit data always starts at an address divisible by 4, i.e., xxx0, xxx4, xxx8, xxxC.


blabla .MACRO
; If necessary, the macro should insert the appropriate number of NOPs here
STP
.DWORD $12345678 ;must be at ADDRESS /4
.ENDM ...

You're welcome.
I have another problem with .MACRO. Error: ERROR E037: Unrecognized instruction/directive/macro name. ROW 4, FILE

Error information:
ERROR E037: Unrecognized instruction/directive/macro name.

I've checked now.
It seems the error occurs if the macro name begins with a capital letter.

I'm having trouble with the .MACRO instruction in Kowalski Simulator. I'm trying to compile the example code based on the HELP file in the latest version of the program, 1.4.0.9, and it's not working.
Put: .MACRO chr ; character printing
LDA #chr ; tru ‘chr’
JSR PRINT
.ENDM

I'd like to present my system, which I've been working on for some time.
It's based on the popular STM32H750 microcontroller, which can be programmed to emulate older computer systems.

Currently, it can be used to run programs for the ...

Let me quote Gordon Welchman, who became head of Huta 6 at Bletchley Park, who wrote: "Hut 6 Ultra would never have been built if we hadn't learned from the Poles at the last minute details about both the German military version of the commercial Enigma machine and the operational procedures in use ...

“Breaking the Code” is probably the source of all this constant nonsense about Enigma and Turing.

If anyone is interested in history, the movie "Enigma Secret " is basically based on historical events.

I wonder how long the lie that Turing broke the Enigma will persist in the public sphere?
No, Turing didn't break the Enigma, because that was accomplished by a team of three Polish cryptologists: Marian Rejewski, Jerzy Różycki, and Henryk Zygalski.
Turing's contribution was a machine that allowed ...

I looked at your schematics, and they look correct. You wrote that it resembles the Apple II and TI-99/4A. I see some similarity to Apple II and TMS9918A-based graphics cards, of which there were several for the Apple II, such as those shipped with the LCSI Sprite Logo language.
I think you're still ...
