Explicitly Release Memory or Delete Variable

You have only those two keywords for explicit memory release (delete, ArrayFree()).

Thanks Ovo, for ur advice! Yet, this may not solve the purpose of releasing memory connected to a variable, which is neither an object nor an array; will it?

No, you have to rely on their natural life cycle.

Ok. I was actually checking if I can delete them anywhere within the program. Thanks.

My understanding of this is MQL is based on C++, which as far as I know doesn't have automatic memory collection like Java does.
