Reverse Polish Notation

If you create XML gauges, unless you're doing the most simplistic of gauges, you'll need to have a good understanding of RPN (Reverse Polish Notation, not to be confused with RPM, or Rotations Per Minute).

Here's a decent description of it.

I think I'll put this one in my links section.

  Cool ... I especially like the HP Calculator demonstration. It brings back memories of using one in college. :-)

  Hi!
  
  I have a related question - when you store a value into a variable, is the value popped from the stack?
  
  I.e. if I do this: 0 (>L:MyVariable, number), is the 0 still on the stack (so I can store it into the next variable) or do I need to specify it again?
  
  Thanks,
