Proof: Write Stmt Control Map At Unchanged 13

Let's prove the following theorem:

if the following are true:

the line at time 13 = 3
the tab at time 13 = 0
statement at line 3, tab 0 = else:
Control Map at time 13 = [ entry 0: (pair ("if", True)), [ ] ]

then Control Map at time 14 = [ entry 0: (pair ("if", True)), [ ] ]

Given

1	the line at time 13 = 3
2	the tab at time 13 = 0
3	statement at line 3, tab 0 = `else:`
4	Control Map at time 13 = [ entry 0: (pair ("if", True)), [ ] ]

Proof Table

#	Claim	Reason
1	Control Map at time (13 + 1) = Control Map at time 13	if the line at time 13 = 3 and the tab at time 13 = 0 and statement at line 3, tab 0 = `else:`, then Control Map at time (13 + 1) = Control Map at time 13 (Else Unchanged (6))
2	Control Map at time (13 + 1) = [ entry 0: (pair ("if", True)), [ ] ]	if Control Map at time (13 + 1) = Control Map at time 13 and Control Map at time 13 = [ entry 0: (pair ("if", True)), [ ] ], then Control Map at time (13 + 1) = [ entry 0: (pair ("if", True)), [ ] ] (Transitive Property of Equality)
3	13 + 1 = 14	13 + 1 = 14 (Fixed Value Statement)
4	Control Map at time (13 + 1) = Control Map at time 14	if 13 + 1 = 14, then Control Map at time (13 + 1) = Control Map at time 14 (Substitution)
5	Control Map at time 14 = [ entry 0: (pair ("if", True)), [ ] ]	if Control Map at time (13 + 1) = Control Map at time 14 and Control Map at time (13 + 1) = [ entry 0: (pair ("if", True)), [ ] ], then Control Map at time 14 = [ entry 0: (pair ("if", True)), [ ] ] (Transitive Property of Equality Variation 2)
