Proof: Do Control Map At Unchanged 40

Let's prove the following theorem:

if the following are true:
  • expression state at time 40 = "iterate_args"
  • Control Map at time 40 = [ entry 0: (pair ("while", 2)), [ ] ]

then Control Map at time 41 = [ entry 0: (pair ("while", 2)), [ ] ]

Given
1 expression state at time 40 = "iterate_args"
2 Control Map at time 40 = [ entry 0: (pair ("while", 2)), [ ] ]
Proof Table
# Claim Reason
1 Control Map at time (40 + 1) = Control Map at time 40 if expression state at time 40 = "iterate_args", then Control Map at time (40 + 1) = Control Map at time 40
2 Control Map at time (40 + 1) = [ entry 0: (pair ("while", 2)), [ ] ] if Control Map at time (40 + 1) = Control Map at time 40 and Control Map at time 40 = [ entry 0: (pair ("while", 2)), [ ] ], then Control Map at time (40 + 1) = [ entry 0: (pair ("while", 2)), [ ] ]
3 40 + 1 = 41 40 + 1 = 41
4 Control Map at time (40 + 1) = Control Map at time 41 if 40 + 1 = 41, then Control Map at time (40 + 1) = Control Map at time 41
5 Control Map at time 41 = [ entry 0: (pair ("while", 2)), [ ] ] if Control Map at time (40 + 1) = Control Map at time 41 and Control Map at time (40 + 1) = [ entry 0: (pair ("while", 2)), [ ] ], then Control Map at time 41 = [ entry 0: (pair ("while", 2)), [ ] ]
