Proof: Do Control Map At Unchanged 50

Let's prove the following theorem:

if the following are true:

expression state at time 50 = "begin_expr"
Control Map at time 50 = [ entry 0: (pair ("while", 2)), [ ] ]

then Control Map at time 51 = [ entry 0: (pair ("while", 2)), [ ] ]

Given

1	expression state at time 50 = "begin_expr"
2	Control Map at time 50 = [ entry 0: (pair ("while", 2)), [ ] ]

Proof Table

#	Claim	Reason
1	Control Map at time (50 + 1) = Control Map at time 50	if expression state at time 50 = "begin_expr", then Control Map at time (50 + 1) = Control Map at time 50 (Insn Count Begin Expression (7))
2	Control Map at time (50 + 1) = [ entry 0: (pair ("while", 2)), [ ] ]	if Control Map at time (50 + 1) = Control Map at time 50 and Control Map at time 50 = [ entry 0: (pair ("while", 2)), [ ] ], then Control Map at time (50 + 1) = [ entry 0: (pair ("while", 2)), [ ] ] (Transitive Property of Equality)
3	50 + 1 = 51	50 + 1 = 51 (Fixed Value Statement)
4	Control Map at time (50 + 1) = Control Map at time 51	if 50 + 1 = 51, then Control Map at time (50 + 1) = Control Map at time 51 (Substitution)
5	Control Map at time 51 = [ entry 0: (pair ("while", 2)), [ ] ]	if Control Map at time (50 + 1) = Control Map at time 51 and Control Map at time (50 + 1) = [ entry 0: (pair ("while", 2)), [ ] ], then Control Map at time 51 = [ entry 0: (pair ("while", 2)), [ ] ] (Transitive Property of Equality Variation 2)
