If you are running in debug mode, you can click the right mouse button while the cursor is in the debug/runtime window and a pop-up menu will appear - select "View Memory", and another window will popup with memory displayed. In the memory location bar at the top of this window, type in
"0x3000" if your variable is at "0x3000". You can also access this function from one of the top menu lists in CW. The window values may not be updated until you hit a "stop" in the debug screen.
I hope that this helps to answer the question.
