The instructions in Visual Turing
- They can be combined in the graph-programs of the machines. Any machine
has a start instruction - the instruction which is executed first. That
instruction has a left arrow like in the figure below

The start instruction marking
- In the process of the debugging it is useful to have breakpoints on
some instructions. Use the context menu or the properties dialog to do
this. An instruction with breakpoint looks like the figure below. Don't
forget that the breakpoints stop the program only in visual debug mode.
