Altering a variable in a loop.

[HenrikOlsson]

Hi,
I think that should work. However, since Setpoint doesn change if Setting doesn't change there's no need to assign a value to SetPoint each time thru the loop.
You can move it into the If SettingChanged section, something like:

If SettingChanged THEN
    LOOKUP Setting, [12,23,34,45,56], DutyCycle            ' Assign inital value to DutyCycle variable
    LOOKUP Setting, [0, 2, 5, 9, 14, 17], SetPoint         ' Assign value to setpoint variable    
    SettingChanged = 0                 ' Clear flag
EndIf

Or you could do something like:

IF SettingChanged THEN
  Select Case Setting
    Case 1
       DutyCycle = 12   'Initial dutycycle for setting 1
       SetPoint = 0
   Case 2
       DutyCycle = 23
       SetPoint = 2
   Case 3
       '.......
       '.......
End Select

Try it, see which works best, compiles to the smallest code, is easiest to maintain and understand etc etc.

Good luck!
