使用相对指针寻址数据（x86-32汇编程序）

   call @f
   dd 42 ; data
@@:
   pop eax ; eax contains offset of data
   mov eax, cs:[eax]

   call base
base:
   pop ebp
   sub ebp, base ; to use small offsets, -128 to +127, and smaller instruction size
   ;....
   mov eax, cs:[ebp+dataN-base] ; dataN-base is called "delta-offset"
   ;....
data1:
   dd 100
   ;....
dataN:
   dd 200

mov    edx, cs:[eax]
