Using Single-Step Commands

While different programs have different requirements, the most common debugging stepping mode is to set group focus to Control and the target to Process or Group. You can now select stepping commands from the Process or Group menus or use commands in the icon bar.

The following applies to all single-step command:

• To cancel a single-step command, put the mouse pointer in the Process Window and select Group > Halt or Process > Halt.
   
• If your program reaches a breakpoint while stepping over a function, TotalView cancels the operation and your program stops at the breakpoint.
   
• If you issue a source-line step command and the primary thread is executing in a function that has no source-line information, TotalView performs the corresponding instruction step instead.

When TotalView steps, it steps a line at a time. This means that if you have more than one statement on a line a step instruction executes all the instructions.
