Hi,
Suppose I have an array called ArrayA, and I want to save a
reference to it.
ArrayB = ArrayA
So that I can now use ArrayA for something else:
ArrayA = ""
I can now use ArrayA for something else; however, ArrayB still
contains the array in case I need it.
The question is this: Is the ArrayB = ArrayA statement a "reference
assignment", or does it involve an item by item copy?
The reason I ask is that in my case ArrayA may be at a given time
rather large, and if it involves an item by item copy, it seems to me
it might take a long time to do the copy; on the other hand, if it is
just a reference assignment, then it would be instantaneous.
I know that in the case of object, it is just a reference assignment,
but I don't know for arrays and other variables what it is doing.
Anyone knows?
Best regards,
Edgard
