	~~== The Original Code ==~~		#REDIRECT [[ist:Code Generation/Example 2]]

	~~Consider the following~~ [[~~S9 (language)\|S9]] function~~:

	~~<c>~~
	~~string a = "batata";~~
	~~int s9() -> 0 {~~
	a!
	}
	~~</c>~~

	~~== Postfix~~ Code ==

	~~The Postfix code for the above function is as follows:~~
	~~{{CollapsedCode\|Postfix code\|~~
	~~<asm>~~
	~~;--- declaring the string literal~~
	~~RODATA~~
	~~ALIGN~~
	~~LABEL _L123 ;; automatic label~~
	~~STR "batata"~~
	~~;--- declaring the global variable "a"~~
	~~DATA~~
	~~ALIGN~~
	~~LABEL a~~
	~~SADDR _L123 ;; automatic label~~

	~~;--- this is the main function (note that "s9" translates to RTS's "_main")~~
	~~TEXT~~
	~~ALIGN~~
	~~GLOBL _main, FUNC~~
	~~LABEL _main~~
	~~ENTER 0~~

	~~ADDR a~~
	~~LDINT~~
	~~EXTRN prints~~
	~~CALL prints~~
	~~TRASH 4~~

	~~INT 0~~
	~~STFVAL32~~
	~~LEAVE~~
	~~RET~~
	</~~asm>~~
	}}

	~~== Compiling and Running ==~~

	~~To test the first example, the S9 compilation process is as follows:~~

	~~s9 batata.s9~~
	~~yasm -felf batata.asm~~
	~~ld -o batata batata.o -lrts~~

	~~To test the second program directly, [[pf2asm]] can be used:~~

	~~pf2asm batata.pf~~
	~~yasm -felf batata.asm~~
	~~ld -o batata batata.o -lrts~~
