I forget who said it (perhaps Larry Wall?), but a thought I have always liked is, There is no real difference between scripting and programming, but the ones who call it programming usually do it better.

Seriously, if your approach to programming is to walk through what you need to do in order, and write code fairly linearly to do the task, then what you are doing is scripting. Even if you are doing it in C. Even if some of the steps you are calling are from complex libraries.

On the other hand if you are trying to factor and organize your code from the get-go, then you are probably programming. No matter what language you are writing in.

By my definition I have personally seen scripts written in C, and programs in DOS bat files. In my books it isn't what language you are using, or what task you have accomplished. Rather it is how you went about doing it.
