if the following are true:
the PC at time 0 = 0
instruction #0 is `store src=3 addr=6 imm=0`
instruction #1 is `store src=4 addr=6 imm=1`
instruction #2 is `store src=5 addr=6 imm=2`
value of cell 3 at time 0 = 13
value of cell 4 at time 0 = 11
value of cell 5 at time 0 = 20
value of cell 6 at time 0 = 7
then value of cell 8 at time 3 = 11
