	"global somename" only tells the Python interpreter that all
references WITHIN a function definition to "somename" really are
references to "somename" at the MODULE level. 


-=-=-=-=- amodule.py

name1 = 123
name2 = 456
name3 = 789

def afunc(x):
	global name1
	z = x + name1	#okay, it is using the module name1
	name1 = z		#still okay
	y = x + name2	#okay so far, will look up to the module level
	e = y + name3	#due to the next line, this will error
	name3 = e		#no global, name3 is local, and above is undefined
