According to the example above we can present this menu like a flow-chart.
The flow-chart presents the menu structure, we have a main menu(M0 level) and
one sub-menu(M1 level), the elements in rectangles are macros – the final step for
each element in menu or sub-menu.
You can put maximum 10 elements in each menu or sub-menu. The maximum
length of menu value which displays on the screen is 12 characters. The maximum
level of menu is 4, so the longest way to get to the macro is 4 steps.
