I normaly do something like this
typedef struct { u8 MenuID, bool EnterFlag, bool ** Handler (bool EnterFlag)} MenuTypeDef;

than we just loop it
while (1) Menu.EnterFlag = Handler[Menu.MenuID].Handler (Menu.EnterFlag);
when it goes to handler, it resets EnterFlag and update screen
when it goes to another handler, it sets EnterFlag and let another handler update the screen data
So, basicaly, only one string are used.

while (1) Menu.EnterFlag = Menu.Handler[Menu.MenuID].Handler (Menu.EnterFlag);
sorry, small mistake. Handler is also part of menu structure.
