# Simple MIPS program that computes:
#    num1 = num1 + num2
# where num1 and num2 are numbers stored in memory.

	.data
num1:	.word 5            # place decimal 5 in memory
num2:	.word 6            # place decimal 6 in memory 
	
	.text
	.globl main
main:	la $s0, num1       # la = load address (psuedo-instruction not in book)
	la $s1, num2
	lw $t0, 0($s0)     # $t0 <- value at num1
	lw $t1, 0($s1)     # $t1 <- value at num2
	add $t2, $t0, $t1
	sw $t2, 0($s0)

	# There are also useful psuedo-instructions that make it possible
	# to lw or sw directly from/to a label: 
	# lw $t2, num1       
	# sw $t2, num1
