Recusive function inside a function can't find itself.

No.  The easiest thing to do is move the definition of fill_code_list() 
out of the body of display_codes() (perhaps with a leading underscore). 
 The only thing nesting a function definition does is to put the name 
binding into the function namespace (where the nested function cannot 
find it).  Or you can try to find a posting of mine from a couple of 
years ago on nested recursive functions.
