====== Stepping Through Program Execution ======

You have two options when stepping through source code. You can:

  * step over calls to functions and subroutines;
                                                                                 
- OR - 

  * trace into functions and subroutines. The function key you choose to execute a line of code governs how the line will execute.

The two procedures that follow, explain how to step over and trace into a function or subroutine.
