我想在我的代码中使用这样的东西：

.data?
my_macro_var db MAX_PATH DUP (?)

.code

mov esi, offset my_macro_var 
my_macro esi, "hello and bye"

为此，我创建了这个宏，但我得到了一些错误，我不能解决。

my_macro macro reg, characters  
 LOCAL v1,v2,v3
 LOCAL c1,c2,c3,c4,cTotal

 v1 TEXTEQU  %(@SizeStr(<characters>)) -2 ;; -2 is for the double quote
 v2 textequ %(v1/4) 
 v3 = 0 

 ;% echo @SubStr(<characters>, 2, 4)   

 repeat v2     
     c1 Substr <characters>,v3,1

     cTotal equ c1
     mov dword ptr [reg+v3], cTotal
     v3=v3+4
 endm

endm

我想要这个结果。

mov dword ptr [esi+00d], 'lleh'
mov dword ptr [esi+04d], 'na o'
mov dword ptr [esi+08d], 'yb d'
mov dword ptr [esi+12d], 'e'

这是我得到的错误：

Code.asm(14) : error A2090: positive value expected

my_macro(16): Macro Called From
Code.asm(14): Main Line Code

Code.asm(14) : error A2006: undefined symbol : a

我想我的问题将得到解决，如果我可以使用substr和连接4变量.
