; Starts the Radio Button Block
; You should pass a variable that keeps the selected section
; as the first parameter for this macro. This variable should
; be initialized to the default section's index.
;
; As this macro uses $R0 and $R1 you can't use those two as the
; varible which will keep the selected section.
