If-else macros? To my knowledge, I'm the first/only one in this community who makes real macro language/s: .if/.else/.while/.repeat/etc for X86+ARM, aside from the macros included with FASM+ARM. For years, I've searched this message board and have not found any good runtime macros so I had to learn/write everything by myself. By this time, I've contributed 1,000s of unique macros.

TCP/IP!!!!!!!!!!!!!!!!!!! Finally!
(I need to change my signature! I feel so proud! (Not good to boast about yourself.....)

macro imm32 reg,immediate {
  mov reg,(immediate) and $FF
  orr reg,(immediate) and $FF00
  orr reg,(immediate) and $FF0000
  orr reg,(immediate) and $FF000000
}    

macro movi a, b {
 local n
 if (b)=-1 | (b)=0FFFFFFFFh
  mvn a, 0
 else if (b)>0 & (b)<255
  mov a, (b)
 else
  mov a, (b) and 0FFh
  n=(b) and 0FF00h
  if n<>0
   orr a, a, n
  end if
  n=(b) and 0FF0000h
  if n<>0
   orr a, a, n
  end if
  n=(b) and 0FF000000h
  if n<>0
   orr a, a, n
  end if
 end if
}

        push   (r11)                                     ;

Macro return                                             ;

macro return v {
 if ~v eq           ; if parameter was sent
  movi r0, v        ; or your imm32/ldr #
 end if           
 pop \{r4-r11, pc\} ; return
}    

I need help, too. I still haven't got Alex Chadwick's ARM USB driver working. Did you link to libcsud.a? Tell me how to do this and I guarantee NATIVE ARM assembler+compilers+BASIC+C+Z for RPI Message me sometime.

push {r4-r11, lr\} ; start
pop {r4-r11, pc\}  ; return    

pop \{r4-r11, pc\}    

I see, my OS image was deleted.

push \{r0-r5, r10\}
; ...
pop \{r0-r5, r10\}    

Dex4u: For the second problem, because it is within another macro you need to escape the closing curly bracket:

Code:

push {r4-r11, lr\} ; start
pop {r4-r11, pc\}  ; return    

i have never claim to be an experienced macro programmer

And I ported MessiahAndrw's 3D Engine to POSx86 (Not much work)

I guess it's the toughest thing todo when you have no documentation available.

All I need to learn USB programming is the book by Benjamin Lunt.

So I ask one question. Have you every thought of or have written an operating system?
