After simple assignment by := both variables points to the same array body.

because both vars uses the same array after above assignment.
If you do not like it and you want to make full array clone before
assigning array reference to variable then you should make it in the
same way as in Clipper and instead of:
aVar2 := aVar1
you should use:
aVar2 := AClone( aVar1 )
