# simple example of returning from a function
# loops because main does not save return address

	syscall

	jal	f			# set $ra to following address

	li	$v0, 4
	syscall

	li	$v0, 0			# return from function main
	jr	$ra			# breaks because $ra has been changed since main called


f:
	la	$a0, string2		# printf("in function f\n");
	li	$v0, 4
	syscall
	jr	$ra			# return from function f
