Hi oko1 , wonderful dude, I tried the above snippet and it works perfect. but i got a doubt , i tried expanding the function names and still i got only three functions at a time..

display
-- audit
-- bass

elucent
-- audit
-- check

main
-- display
-- elucent
-- audit
-- check

audit 
-- hi_oko1
 

Output: 
So the new output should be like this:
main display audit hi_oko1
main display bass
main elucent audit hi_oko1
main elucent check
main audit


But still im getting the same o/p:-
main display audit
main display bass
main elucent audit
main elucent check
main audit hi_oko1
