Displaying and modifying variables
The Variables tab in the Debugger shows the names and values of any global and Timeline
variables in the SWF file selected in the display list. If you change the value of a variable on the
Variables tab, you can see the change reflected in the SWF file while it runs. For example, to test
collision detection in a game, you can enter the variable value to position a ball in the correct
location next to a wall.
The Locals tab in the Debugger shows the names and values of any local variables that are
available in the line of ActionScript where the SWF file is currently stopped, at a breakpoint or
anywhere else within a user-defined function.
