IL body

LD	var_1	(* Load var_1 in accu *)
		(* Since bracket expression follows, save content of accu; process expression in brackets first *)
XOR(	var_2	(* Load var_2 in accu *)
OR	var_3	(* Perform OR of var_3 with accu; store result in accu *)
)		(* Perform XOR of saved accu content with actual content of accu; store result in accu *)
ST	var_4	(* Store accu in var_4 *)
