Declaring a Function Before it is used

Also, can anyone tell me if there is a way to declare a function before it
is used.

If not, how do you handle things like:
Run Function A, which calls Function B
Function B calls Function C
If statement then
  Function C calls Function D
else
  Function C calls Function A
end if

This seems impossible to handle if you can't declare Function A ahead of
time, because you can't move it ahead of Function C to solve the problem,
since that causes a problem of not being able to call Functions B and C from
Function A
