The instruction to which the program counter is pointing at is darkened as shown in
Figure 3.41. Executing this command will also bring the instruction pointed to by the program
counter to the first line in the assembly window.
Set Breakpoint
To set a breakpoint at an instruction in the Source window, take the following actions:
1. Place the mouse cursor at the instruction in the source window.
2. Press the right mouse button to bring up the debugger command menu.
3. Select the Set Breakpoint command.
After these, a right-pointing red arrow will appear to the left of the instruction at the break-
