RE: Basing Pointer Questions

I think of based variables and their pointers as if they were regular
variables.  To turn your question around a bit:

MyVar = 100
AnotherVar = MyVar
What is the value of AnotherVar?

>2.) If AnotherBasingPointer is pointing to

>I reallocate 1000 bytes to AnotherBasingPointer,

AnotherVar = 1000
What is the value of MyVar?

Hope this analogy is useful.
