I don't think "scripting language" is well enough defined to say. Scripting as an activity might be ... something about automating a few manual steps. But the point where your "script" becomes complicated enough to be a "program" is going to be hard to pin down.
I think people are saying "scripting language" when they mean open source, dynamic, interpreted language, just because they don't have a better word for it. Most scripting langauges are as "real" as programming languages get. I wouldn't belittle work done in any of them. Except maybe Windows Batch.
A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
