There is a scripting language being used by people on this forum. I cannot think of its name. It is something with IT in the name. TestIT maybe? It has the capability to know what line of code was running when it hit an error. I have seen the software mentioned in this forum and do not know where. I think that it can be used as both a language like vbscript and also can do testing.
I know these clues are scarce, but it is all that I remember.
