Fasm 1.73

Code:

macro vequ a,[p] {
      ii equ 1
      forward
      a#.ii equ p
display a#.ii;This show eax. But how show oo.1 or oo.2 ? Or what name created ?
      ii equ ii + 1
display ii+48 ; show 2,3,4,5
      }  
;i want get oo.1 equ eax.   oo.2 equ ebx   oo.3 equ ecx
vequ    oo,eax,ebx,ecx,edx   

mov     edx,oo.2                  ;fasm error undefined symbol oo.2

Use rept

Code:

rept 1 x:ii+1 { ii equ x }

When you use equ like you end up with ii+1+1+1+1+1+1. It just keeps appending "+1" each time.

I not understood, how rept help me get oo.1,oo.2,oo.3 ?

I try this.

Code:

macro vequ a,[p] {
      ii equ 0
      forward      
      rept 1 x:ii+1 \{ ii equ \x \}
      a#ii equ p
       display a#.\#ii ; show oo.#1 and fasm error
      
      }

Sometimes fasm logic not clear.
And driving me crazy.

Its right ?

Code:

macro vequ a,[p] {
      ii equ 0
      forward      
      rept 1 x:ii+1 \{ ii equ x \}
      a#.#\ii equ p      ;must do oo.1 then oo.2 then oo.3 or not ?
      } 
vequ    oo,eax,ebx,ecx,edx

Code:

;This work fine.
rept 3 n:1 { oo.#n equ n }
mov     edx,oo.2  ;no error. Compiled ok.

;But this error
macro vequ a,[p] {
      ii equ 0
      forward    
      rept 1 x:ii+1 \{ ii equ x
      a#.\\#ii   equ p           ;This fasm error oo.#1 equ eax
a#.\#ii  equ p ;This ok. But in code error mov edx,oo.2 undefined oo.2
       \}      
      } 
vequ    oo,eax,ebx,ecx,edx
mov     edx,oo.2 ;error  undefined oo.2

F..ck. Fasm abracadabra.
I do this !

Code:

macro vequ a,[p] {
      ii equ 0
      forward
      rept 1 x:ii+1 \{ ii equ x
      a#.\#x  equ p
     \}
      } 

vequ    oo,eax,ebx,ecx,edx

mov     edx,oo.2 ; no error. Get mov edx,ebx
