Using jump register (jr $a)
jumps to instruction referenced in $a
suppose Label is memory location containing addresses L0, L1, L2. ($4=k*4)
lw $10,Label($4) # $10 = Label[k]
jr $10 # jump $10
L0: addi $20,$0,20 # $20 gets 20
j BREAK
L1: addi $20,$0,10 # $20 gets 10
j BREAK
L2: addi $20,$0,11 # $20 gets 11
BREAK: continue whatever here
