• the line at time t = i
• the tab at time t = j
• statement at line i, tab j = "while" statement with condition (function call with name: name and arguments: args)
• Expression Stack at time t = [ [ ], [ ] ]
• Value Stack at time t = [ [ True, [ ] ], [ ] ]

then Control Map at time (t + 1) = result of storing (pair ("while", i)) at key: j in map: (Control Map at time t)
