Is there a debugger that runs under Menuet?
What debugging tools/practices are you people using?

I'm using DEBUG.INC if needed. AFAIK no other tools available.

What for do you need an example??? It's just a set of macroses (don't use procedures directly, they won't save you flags and registers) which output something (string, decimal, hex, char) to debug board. The code is there (debug.inc), it's pretty self-explaining:

Code:

macro debug_print str
{
   local ..string, ..label

   jmp ..label
   ..string db str,0
  ..label:

   pushf
   pushad
   mov  edx,..string
   call debug_outstr
   popad
   popf
}

dps fix debug_print

macro debug_print_dec arg
{
   pushf
   pushad
   if ~arg eq eax
     mov  eax,arg
   end if
   call debug_outdec
   popad
   popf
}

dpd fix debug_print_dec

;---------------------------------

        push -'0'       ;2

        xor edx,edx     ;2
        div ecx         ;2

fasm1.56 doesnt want's to compile this:

Code:

mcall 63, 1

is this a bug or me being dum? Confused

btw, is debug.inc distributed elsewhere than here on this forum?

Replace it with

Code:

mov eax, 63
mov ebx, 1
int 0x40

BTW Debug.inc is distributed with RE#8.

i know, but why doesnt the shorter code works?
let me gues, its a function in the macros.inc distibuted with re#8? Very Happy

It's mine and Ivan's macroses to code Menuet applications easier:

Code:

macro mpack dest, hsrc, lsrc { ; Ivan Poddubny
 if (hsrc eqtype 0) & (lsrc eqtype 0)
  mov dest, (hsrc) shl 16 + lsrc
 else
  if (hsrc eqtype 0) & (~lsrc eqtype 0)
   mov dest, (hsrc) shl 16
   add dest, lsrc
  else
   mov dest, hsrc
   shl dest, 16
   add dest, lsrc
  end if
 end if
}

macro __mov reg,a,b { ; mike.dld
 if (~a eq)&(~b eq)
  mpack reg,a,b
 else if (~a eq)&(b eq)
  mov reg,a
 end if
}

macro mcall a,b,c,d,e,f { ; mike.dld
 __mov eax,a
 __mov ebx,b
 __mov ecx,c
 __mov edx,d
 __mov esi,e
 __mov edi,f
 int   0x40
}

You can find them in MACROS.INC file from russian distro (RE#8).
EXAMPLE.ASM becomes:

Code:

  use32
  org    0x0

  db     'MENUET01'
  dd     0x01
  dd     START
  dd     I_END
  dd     0x100000
  dd     0x100000
  dd     0x0
  dd     0x0

include 'MACROS.INC'

START:

red:

    call draw_window

still:
    mcall 10

    cmp  eax,1
    je   red
    cmp  eax,2
    je   key
    cmp  eax,3
    je   button

    jmp  still

  key:
    mcall 2

    mov  [Music+1], ah

    mcall 55, eax, , , Music

    jmp  still

  button:
    mcall 17

    cmp   ah, 1
    jne   still

  .exit:
    mcall -1

draw_window:
    mcall 12, 1
    mcall 0,<200,200>,<200,50>,0x02AABBCC,0x805080D0,0x005080D0
