What I would like to do is know the rate of change for pedals / steering wheel input on a dashboard and display a status. I would like to see when I am pressing the throttle too hard or releasing the brake too quickly or turning the steering wheel too fast.


The general formula for this would be:

(CurrentInputState - PreviousInputState) / Elapsed Time = Result


With a general validation of:


If Result > MaximumInputChange Then DisplayBadStatusNotifier


Where I am falling down (and I admit it's likely because I am very new to SimHub) is that I don't seem to be able to reset the value for 'PreviousInputState'. Normally, I would:

code a variable for PreviousInputState and set its initial value

(loop start)
  Gather CurrentInputState in realtime
  Run the formula
  Validate the Result
  Assign CurrentInputState value to PreviousInputState
(repeat loop)

It appears that I can assign a variable and initial value to PreviousInputState with an ini file in the NCalcScripts folder (ref: removed link ) and I can run the formula and evaluate the result in the binding engine (ref: removed link ---Introduction), but then I fall down on the PreviousInputState reassignment... How does one assign a new value to a  variable in NCalc / SimHub? Any help would be appreciated!
