5. A debug editor similar to the routine editor shows up with the debugger positioned on
the first line of the stored procedure, which is theCREATE PROCEDURE statement. The
current line where the debugger is positioned is always highlighted and a small arrow
will be shown on the left margin. This is shown in Figure 8.24.

6. Set break points: In the Debug perspective there is a Debug task bar, as shown in
Figure 8.25.

The arrow icons on the Debug task bar provide the Step Into, Step Over, Step Out and
other features while debugging a program (in this case, a stored procedure):
• The Step Into arrow ( ) positions you inside the next routine call at the
currently executing line of code.
• The Step Over arrow ( ) positions you after the next routine call (without
entering it) at the currently executing line of code.
• The Step Return arrow ( ) positions you outside a routine which has been
stepped into.
• The Resume icon ( ) lets a suspended debug target continue running.
• The Suspend icon ( ) halts the currently selected thread and temporarily
stops it from running in a debug target. Once the selected thread is suspended
you can then examine its stack frames.
• The Terminate icon ( ) terminates the debug session
