Resetting the Stack Frame
After moving around your source code to look at what’s happening in different places, you can return to the executing line of code for the current stack frame by selecting the View > Reset command. This command places the PC arrow on the screen.
This command is also useful when you want to undo the effect of scrolling, or when you move to different locations using, for example, the View > Lookup Function command.
If the program hasn’t started running, the View > Reset command displays the first executable line in your main program. This is useful when you are looking at your source code and want to get back to the first statement that your program executes.
