Question about using "include"

[kcvinu]

Hi all, Lets assume that i have a 3 nim source files like this. 
    
    
    #file1.nim
    var v1 : int = 1500
    #----------------------file1 ends here-----------
    
    #file2.nim
    var v2 : int = 2500
    #----------------------file2 ends here-----------
    
    #file3.nim
    include file1
    include file2
    
    var v3 : int = 3500
    #----------------------file3 ends here-----------
    
    
    Run

I can use v1 & v2 in file3. It's okay. I know that nim is considering file1, 
file2 & file3 as single file in this case. But how do i use v3 in file1 or 
file2 ?
