Dispose Memory for a Dynamic Array

[Alejandro Moreno Aguirre]

I have declared a dynamic like:
sizes: Array Of Integer;

and allocated memory for it:
SetLength(sizes,10);

Would I dispose the memory allocated for this array, as dynamic memory that
it is?
I have tryed with Dispose and FreeMem but in both cases it hadn't worked.

What about setlength(sizes, 0) ?

You don't have to release dynamic arrays. Their memory is automatically
released when the array goes out of scope or the record, object, or class
instance owning them is released. You can, if you want, release the memory
earlier by setting their length to zero.

You don't have to. If you want to get rid of it, set each variable
pointing to it to nil, but normally Delphi will insert code that handles
this automatically.
