apart from initializing data, structures below can be used to
speed up access to data and let cc65 to generate better code
e.g. if you have menu defined as TopMenu and you want to change the number of
menu items use:
((struct menu*)&TopMenu)->number=newNumber;
This will translate into single lda/sta pair
