I am taking an online course on "Transitioning from VB6 to VB.NET."

In the section on structures, it said that structures are value-type data, not reference-type, and that they therefore are saved on the stack, rather than the heap.

In what I have been able to find at MS.com's MSDN site, and elsewhere, I am starting to suspect that there is a region in .NET called the stack which is different from the procedure-call stack.

Stacks (virtually always) are First-In, Last-Out arrangements. How can an arbitrarily, randomly accessED variable be handled on a FILO stack?

I really could use some illumination here...

(I have programmed in C, a little in C++, and I make my living writing and upgrading a large VB IIS application. I understand programming environments, but not this feature--as described to me so far, anyway.)
