If Test True Tab Property

If the "if" statement test evaluated to True at time t, then at time t + 1, the tab number is incremented by 1. More formally,

if the following are true:

  • the line at time t = i
  • the tab at time t = j
  • statement at line i, tab j = if test:
  • expression state at time t = "end_expr"
  • Return Value at time t = True

then the tab at time (t + 1) = j + 1

For example,

if the following are true:

  • the line at time 10 = 1
  • the tab at time 10 = 0
  • statement at line 1, tab 0 = if __eq__(3, 3):
  • expression state at time 10 = "end_expr"
  • Return Value at time 10 = True

then the tab at time (10 + 1) = 0 + 1

Try stepping through the simulator to see the tab number increment by 1.
