Hi I'm a supporter of tniASM and want to be in contact with other tniASM v1.0 users for share interesting macro's and technics.
This assembler is very powerfull and the possibilities are legion.

I will begin first.

; 16bit compare nondestructive all flags as expected
%macro cp hl,bc
and a
sbc hl,bc
add hl,bc
%endmacro

; define word then byte
%macro dwb %n,%n
%def16 #1
%def8 #2
%endmacro

dwb 4000h,2

; 16bit load in 8bit halfs
%macro ld hl,%n,%n
ld hl,#1 <<8| #2
%endmacro

ld hl,200,10

; pallette v9938
%macro rgb (%n,%n,%n)\(#2 <<8| #1 <<4| #3)\%endmacro

dw rgb(1,2,3), rgb(7,6,5), rgb(3,4,5)

I've used it a few times, nice tool. I used the free version at first (http://www.tni.nl/products/tniasm045.zip) and I decided to donate to the project because I liked it.

I dont use the macro functions yet, although I think bifi or guyver800 gave me a macro for something I needed once.

If you want to get in touch with tniasm users, you should definitely visit #msxdev .. the creator of tniasm is there often;) and some users:)

Anyway thanks for your macros, looks nice. I will give them a try sometimes when I get back to coding.

I am a user of tniasm. I have no clue why but I just love the tool. Its fast simple and does the job.

So nobody has macro's for to share.? :-(

Well... I have few additions to Z80N00B.INC:

%macro JP HL  \%def8 E9h\ %endmacro
%macro JP IX  \%def16 E9DDh\ %endmacro
%macro JP IY  \%def16 E9FDh\ %endmacro
%macro POP PC \%def8 C9h\ %endmacro

%macro RST Z,%n
  %if #1 <> 38h
    %error "Illegal RST"
    %def16 0
  %else
    %def16 $FF28
  %endif
%endmacro

%macro RST NZ,%n
  %if #1 <> 38h
    %error "Illegal RST"
    %def16 0
  %else
    %def16 $FF20
  %endif
%endmacro

This is maybe more useful:

CHPUT	equ $a2
CR	equ 13
LF	equ 10

%macro PRINT %s
	call _PRINT
        %% '%def8 '+#1
	%def8 0

%endmacro

_PRINT:
	pop hl
	ld a,(hl)
	inc hl
	push hl
	and a
	ret z
	call CHPUT
	jr _PRINT
	

;Example:

	PRINT "'Hello World!',CR,LF"
	ret

Now encode the others like 125 BASIC commands in macros.

I was wondering, wouldn't it be nice to write structured Assembler? Unfortunately it seems that although tniASM is quite powerful with macros, there are quite a bad limitations that make things pretty hard... Anyway here is my first try.

%INCLUDE "Z80R800.INC"
%INCLUDE "STRUCTURE.INC"


	%ORG $D000

	LD A,[CALCBITS]
	AND A
	IF 'NZ'
	   LD A,[DATA]
	   LD B,8
	   LD HL,0
           
	   LOOP:
	   ;----
	   ADD A,A
	   IF 'C'
	      INC H
	   ELSE
	      INC L
	   ENDIF
	   DJNZ LOOP
	ENDIF
	RET

CALCBITS: %DEF8 $FF
DATA:	  %DEF8 $57

... to make it work you need few macros defined:

Yes, I know... it is not great as it limits the number if IF-commands to ~26... need to look into that some day later. Today I've had enough of this.

OK, so what does this do? Example code of usage?

Example was on the top... As you may notice it reduces the amount of labels you need to write quite a much and makes the source a bit more readable.

Wooow that is fantastic NYYRIKKI.!
GuyveR800 told me once that the goal for tniASM is to compile a form of BASIC direct to machine code.
I thought not possible but this gives me hope
