End Continuing State Property

If the "continue" state is "continuing" and there is a "while" statement in the current tab number - 1, then the "Continue" state is changed to "not_continuing." More formally,

if the following are true:

  • the line at time t = i
  • the tab at time t = j
  • "continue" state at t = "continuing"
  • value at (j - 1) in map (Control Map at time t) = control_value
  • control_value describes a loop = True

then "continue" state at (t + 1) = "not_continuing"

If LW Python finds a "while" statement on the current tab - 1, then the "continuing" state is finished, so it is changed to "not_continuing."

For example,

if the following are true:

  • the line at time 37 = 6
  • the tab at time 37 = 1
  • "continue" state at 37 = "continuing"
  • value at (1 - 1) in map (Control Map at time 37) = pair ("while", 3)

then "continue" state at (37 + 1) = "not_continuing"

Try stepping through the simulator to see the "Continue State" change from "continuing" to "not_continuing."
