Gabor, I recently conducted a study of reusable code, and how prevalent it really was or wasn't in our source. What I found is that on a particular project, there is often room for organizing code in scripts into common modules, which usually requires defining a better design to effectively reuse those modules. Across projects, however, there is not very much code that can be reused. Even after code is organized into modules for one project, a new project will want to redesign those modules, and never reused in the earlier projects.
I would conclude that it is a very good practice to move code from scripts to modules for a particular project, which helps in designing the next project better from an earlier point of time. Over a long period of time, one understands earlier when it is time to organize code into modules. Thanks, David
