Stepping through the execution of Magik program

When a thread is suspended, step controls can be used to step through the execution of the program line-by-line. If a breakpoint is encountered while performing a step operation,  the execution will suspend at the breakpoint and the step operation is ended.

Step over

1. Select a stack frame in Debug View. The current line of execution in that stack frame is highlighted in the editor in Debug Perspective.
2. Click Step Over button [ ] in the view toolbar, or press F6 key. The currently-selected line is executed and suspends on the next executable line.

Step into

1. Select a stack frame in Debug View. The current line of execution in the selected frame is highlighted in the editor in Debug Perspective.
2. Click Step Into button [ ] in the view toolbar, or press F5 key. The next expression on the currently-selected line to be executed is invoked, and execution suspends at the next executable line in the method that is invoked.
