Continuing State Property

If the "continue" state is "continuing" at time t, and there is no "while" statement in the current tab, then at time t + 1, the "continue" state stays in "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 = False

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

The "continue" state will remain in "continuing" until LW Python finds a "while" statement on the current tab.

For example,

if the following are true:

  • the line at time 36 = 6
  • the tab at time 36 = 2
  • "continue" state at 36 = "continuing"
  • value at (2 - 1) in map (Control Map at time 36) = pair ("if", True)

then "continue" state at (36 + 1) = "continuing"

Try stepping through the simulator to see the "Continue State" remain in "continuing" while the "Current Tab" decreases.
