How to display eax register in MessageBox. Please advice.

[Robin1985]

Hello. Please help. Here is a source code:

.386                                           
.RADIX 10                                   
.model flat, stdcall                         

option casemap:none                   

includelib \masm32\lib\kernel32.lib             
includelib \masm32\lib\user32.lib

include \masm32\include\kernel32.inc       
include \masm32\include\user32.inc
include \masm32\include\windows.inc


.data                                           


.code                                           
MsgText db "Works", 0
MsgTitle db "This is a messagebox",0


start:                                         

invoke MessageBox, NULL, ADDR MsgText, ADDR MsgTitle, MB_OK or MB_ICONINFORMATION 
invoke ExitProcess, NULL

end start





Please help me how I can display calculation in MessageBox like "mov eax, 8; mov ebx, eax" and to display 8(ebx) in MessageBox.
