.section .data

#the first parameter, and printf uses  it to 
#find out how many parameters was given and 
#what kind they are.
	firststring:
		.ascii "Hello! %s is a %s who loves the number %d\n\0"
	name:
		.ascii "Jonathan\0"
	personstring:
		.ascii "person\0"
#This could also have been an .equ, but we 
#decided to give it a real memory location 
#just for kicks
	numberloved:
		.long 3

.section .text
	.globl _start

	_start:
		#Note that the parameters are 
		#passed in the reverse order 
		#that they are listed in the 
		#function's prototype
		pushl numberloved	#This is the %d
		pushl $personstring	#This is the second %s
		pushl $name		#This is the first %s
		pushl $firststring	#This is the format string					  #in the prototype
