   can you help me with that?   
      
   i can get the data from a particular memory location using section data, but i   
   want to use registers, cause i want to change the address dynamically which i   
   can'y do with section data

   movsb   
   push test1   
   call _printf   
   ____________________________   
   section .data   
   test1: dd 00h   
      
   then i am getting output of 2 bytes.   
   but if i try to move the address to the register and then try to print it, its   
   not printing anything, no error nothing just blank.section .data

   mov ecx,000000h   
   mov eax, [ecx]   
   push eax   
   push .fmt   
   call _printf   
   ret	   
   	   
   ____________________________________   
   i just wanna know what is there that i am doing wrong.   
      
   In the end, I just want to get the data from a particular memory location   
   using registers not using section data. is there any way?
