execfile in global scope

[v.vayer]

I need to execfile() from a function in order to set value for a global
variable from inside the executed file. I know there are "globals" and
"locals" optional arguments for execfile, but I just can't figure out
how to use them correctly. Here is an example:

Change.py
=========
x = 555

Main.py
=======

def changevar():
execfile("change.py")

x = 111 # global var
changevar()
print x # returns 111 instead of 555

What about :

globdict= globals()

def changevar():
global globdict
execfile("changevar.py",globdict)

x = 111 # global var
changevar()
print x # returns 111 instead of 555

globdict= globals()

def changevar():
global globdict
execfile("changevar.py",globdict)

x = 111 # global var
changevar()
print x # returns 111 instead of 555

execfile("change.py", globals()) # the builtin globals function returns
# the current module's global namespace
# as a writable dict

x = 111 # global var
changevar()
print x # returns 111 instead of 555

... x = 555
... """) ------------------------------
x = 555
------------------------------

>>> dir() ['__builtins__', '__doc__', '__name__']
>>> x = 111
>>> x 111
>>> def changevar():

... execfile('change.py', globals())
... 555
