I just typed same program.

Just a guess: did you first create the global variables A, B, and C before executing the programs? See the note at the beginning of the code listings: In this situation, I have created 3 global variables (A B C) and stored the values (4 5 6) into them. Then each of the following programs is executed...

Part of what I was trying to convey here is what happens when you already have global variables defined when running code with locals using the same names.
