The reason is that I am to make some changes to my app in a particular form. This form has a lot of calls to different modules/func/proc.
With such a thing I will have a road map as to which m/f/p are called from my original form. The first levels are not a big problem for changes its the ones under the first level.
I generally end up forgetting atleast one of them becuase a couple of the ones I have managed have given me a big problem and the users is banging on my door for delivery.
