1911 :: Test if bool var is set

  Is there any way to test if a boolean variable has been set? With strings I've found a variableName != nil works, but this doesn't seem to be the case for most other types.

  A variable is initialized to its "default" which is false for boolean. So you can't check if it is "set".

  Ah alright, explains why that didn't work. Thanks!

  Maybe in this case what you need is enum:

  type State = enum
    sNEED_INIT # First value is the default
    sON
    sOFF
  
  var s: State # By default it is set to the first enum value, in this case, sNEED_INIT
  if s == sNEED_INIT:
    # Stuff
  Run
