Set variable=nothing 3

[LawnBoy]

I see this a lot in the examples provided in this forum. Why is it necessary? When the script exits, do the declared variables somehow persist?

Please enlighten this ignorant newbie...

This is mostly good habbit when playing with OLE automation objects to avoid ghost instances.

And it is mostly dogma. A object going out of scope has exactly the same effect as setting the object to nothing.

I agree that there is not nearly as much need for it as there once was. I don't do it as much as I used to. Having said that, it adds no overhead to the script (except more lines for the coder to read) and it is a good habit if you also code in other languages that don't do garbage collection as seamlessly.
