Consider the following S9 function:
<c> string a = "batata"; int s9() -> 0 {
a!
} </c>
The Postfix code for the above function is as follows:

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
