OK So in that case pass the entry in as a parameter. You can have 
a default parameter of None and if None is passed it effectively 
creates a new entry. The modified(or created) entry is then returned

This avoids the nightmare of accessing the same set of global 
variables from lots of different functions.

Thats OK, It just happens that this is one application where they 
are perfectly suited, but you an do it without...

Well we didn't know until now that that was a requirement.
Personally I'd use two functions, one to dsplay and entry and 
a separate one to edit an entry. You then have a loop something
like:

def is_ok(entry):
   # display entry content
   # ask if user is happy
   # return y/n

def edit_entry(entry=None):
   if entry == None:
      # create new entry with default values
   #foreach field in entry
   #get input per field
   return entry

while not is_ok(entry):
    entry = edit_entry(entry)
save_entry(entry)
