• 4 - 1 = 3
• 46 + 1 = 47

• if the following are true:

  • a = c
  • b = c

  then a = b

• if Control Map at time 46 = [ entry 0: (pair ("while", 2)), [ ] ], then value at (1 - 1) in map (Control Map at time 46) = pair ("while", 2)

• if the following are true:

  • the line at time t = i
  • the tab at time t = j
  • number of lines = i - 1
  • value at (j - 1) in map (Control Map at time t) = pair ("while", while_line)

  then Control Map at time (t + 1) = Control Map at time t

• if the following are true:

  • a = b
  • b = c

  then a = c

• if 46 + 1 = 47, then Control Map at time (46 + 1) = Control Map at time 47

• if the following are true:

  • a = b
  • a = c

  then b = c
