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
