Mad-Assembler (MADS)

Peter... hehe... what can we expect? "texture", "sinus" etc?

flashjazzcat · November 22, 2010

Sounds like a "catarrhi" application...

+JAC! · November 22, 2010

I just tried to expand a STRUCT using the outline viewer, and it doesn't work

Verified, same for .enum. Will check tomorrow. Simply have not used .struct by now.

what can we expect? "texture", "sinus" etc?

All I can say is that has nothing to do with vectors and runs on 64k at full frame rate. The next will be a "traditional" demo which contains two things I started to code back in 1993 - now they have finally become possible. Seems I'm getting wiser with age;-) - well, and the tools get better, especially the assemblers.

Heaven/TQA · November 23, 2010

Peter... maybe you can help me... I have Gridrunner project on my iMac and I am sharing the folder with my Macbook. I can load the main asm file into Eclipse on the Macbook but can not compile it as it seems that the pathes are missing... or what is the mistake I am doing?

I just need post again to send a very big public

Thanks TeBe for creating MADS

My contribution for the Sillyventure is now finished and sent.

Writing object file...
8965 lines of source assembled in 5 pass
39882 bytes written to the object file

This would not have been possible without MADS! It is the biggest demo I've every created in terms of code. And because of ".PROC" and ".LOCAL" the code looks so good, I'd like to print it and put it up the wall in frame. And with the ."IF/.ERROR" during compilation time, I even have automated boundary checks at compile time (DL crossing 1k boundary, branch crossing page boundary). I never imagined that would be possible. So just thanks again!

Tezz · December 9, 2010

I second that, MADS rocks. Thanks to Tebe for all his hard work and support!

I'll look forward to seeing your demo Peter. If it tops your previous work it'll surely win :cool:

I'm learning MADS with a little project right now. I'm slowly grokking the docs, but it seems like the most powerful choice out there.

Creature XL · December 9, 2010

Guys, you should try out the ca65 from the CC65-Suite

@peter:

congrats for finishing a demo for Silliventure. I didn't manage to do the planned intro

Can i have a peek-preview?

Hi TeBe, just found a bug in 1.9.4 which is not there in 1.9.3.

Forward references are sometimes counted as zero page addressing (1 bytes), though they need absolute addressing (2 bytes).

org $4000

.proc main

lda text_block

.endp

.local text_block

.endl

yields this corrupted file. End address should be $4002 instead. This is just the smallest example I could find. The other were more complex.

COM block 1

0000 : 0000 : FF FF 00 40 01 40

0006 : 4000 : AD 02

COM file structure error

0008 : 0000 : 40 | @

- constant PathDelim (uses SysUtils)

- add 3 pass, example work OK

   org $4000

   .proc main
   lda text_block
   .endp


   .local text_block
   .endl

hi there,

is it possible to have full generated list after compilation? i'd like to see all 6502 codes and not a shortened list.

see an example below:

16 FFFF> 0600-0689> A9 00 +   mva #0 sdmctl
17                            copy #osrom,#osram,#0
17                           MWA #OSROM SOURCE\ MWA #OSRAM DEST\ MVA #0 COPY.ROUND\ JSR COPY
17 0605 85 CB A9 C0 85 CC    MWA #OSROM SOURCE
17 060B A9 00 85 CD A9 40 +  MWA #OSRAM DEST
17 0613 A9 00 8D 89 06       MVA #0 COPY.ROUND
17 0618 20 5E 06             JSR COPY

there is a plus "+" :-(

tebe · July 27, 2017

replace MWA by LDA / STA

lda <osrom
sta source
lda >osrom
sta source+1

JohnBlbec · July 31, 2017

i know what does it mean mwa instruction. i was asking something different...

tebe · September 18, 2017

MadAssembler source code, line = 789

margin = 32;

add 'x * 8'

x tab counter

8 size of TAB

default 'margin = 32'

   6 2001 A9 80 8D 00 A0 A9 +  mwa #$80 $a000

'margin = 32 + 8'

  6 2001 A9 80 8D 00 A0 A9 00 8D +    mwa #$80 $a000

'margin = 32 + 8 + 1'

   6 2001 A9 80 8D 00 A0 A9 00 8D 01 +  mwa #$80 $a000

Hi tebe,

I am currently automating my build processes, so I can provide updates for different platforms more easily.

When I compile the mads.pas (2.0.6) with fp-compiler-3.0.0 on Ubuntu 16.04LTS I get the following warnings:

tebe · October 10, 2017

all it's OK, Peter

+JAC! · November 1, 2017

Thanks tebe.

I found I had compiled with "-vh" and most of the hints are actually nonsense, like uninitialized input parameters of type string.
When I compile 2.0.7 with -vw I get only a few warnings. They really look like missing initialization so maybe they are worth while checking.

Which verbosity to you use when you compile?

tebe · November 1, 2017

Delphi 2007: 0 warnings, 0 hints

+JAC! · November 1, 2017

Ok, with standard "-v" I also get no warnings.

I have one request from this thread:

http://atariage.com/forums/topic/254826-mac-osx-how-to-use-altirrawine-and-eclipsewudsnmads-for-development/?do=findComment&comment=3881577

There is a problem, under Linux and OS X, that the "Source: <path>" line is missing in the .lst file. See here: Left windows, right Ubuntu.

tebe · November 2, 2017

try this version JAC

mads_0211.zip

+JAC! · November 3, 2017

Perfect! Works 100% under Linux and looking at the fix I'm sure it'll work under Mac OS X, too. Will try that once my Mac setup is up and running. Thanks, tebe!

Atari_Ace · May 7, 2018

Hi tebe, a minor nit. I noticed that .BYTE doesn't implement additive modifiers like in MAC/65.

     1         ORG $600
     2 FFFF> 0600-0607> EA     NOP
     3 0601 C1 C2 C3      .BY +$80,'ABC'
     4 0604 80 41 42 43      .BYTE +$80,'ABC'

Fortunately .BY does, but perhaps .BYTE and .SBYTE should pick up this feature as well.

+JAC! · May 10, 2018

There are corresponding versions for the screen/string version.

.SB [+byte] bytes and/or ASCII

.CB [+byte] bytes and/or ASCII

Sheddy · May 10, 2018

There's a way to specify "org" on the mads command line. Is there a way to do that with with "opt"? Sometimes would be handy to assemble data without Atari headers.
