Well, long functions are a different probem, best practice would be  
to split a long functions into a number of smaller ones.

But even if the function is long, you don't have to keep scrolling up  
and down, depending on the editor you are using and the platform you  
are running, it's easy enough to either split the window so the  
locals are in the top pane or copy them to a separate window. I  
usually have CodeWarrior running and have a number of windows that  
contain bits of code I have pasted into place that I can re-use later  
on.

All the Best
