After execution begins--you'll probably have typed something like totalview programname--you'll see a five-paned window.
The Process Window

You can get going in several ways. Perhaps the easiest is to click on Step in the toolbar. This gets your program started, which means all the initialization stuff performed by the program gets done but no statements are executed. Alternatively, you could scroll your program to find where you want it to run to, select the line, then click on Run To in the toolbar. Or you could click on the line number, which tells TotalView to create a breakpoint on that line, and then click Go in the toolbar.
If your program is large, and usually it will be, you can use the Edit > Find command to locate the line for you. Or, if you want to stop execution when your program reaches a subroutine, use the Action Point > At Location command to set a breakpoint before clicking on Go.
As you can see, you've got lots of choices. Unlike other debuggers, TotalView gives you choices that allow you to debug your program however you want to debug it.
