Is there a better way to write the case range to test for values between 36" and 48"...the compiler says i need an expression term, not sure how to proceed. -thanks mike 
       
repeat
 case state      'read state of pir
  0 : outa[5]~~  'red led on if no warm body detected
      outa[6..8]~
  1 : outa[5]~   'turn off red led
      outa[6]~~  'yellow led on if warm body detected
      case range               'use ping to see if dog is 36" to 48" from sensor
       >36 and <48 :outa[7]~~  'turn on green led...lucy is in the right spot, treadmill will soon start
                    outa[8]~~  'turn on transistor 4401 to pull in relay and power treadmill

    case range
    37..47: ' do something here
    That is provided range actually delivers values in that area. See also The Manual (rev 1.2, around page 61).

    That would be 36..48 if you want it executed for anything from 36 to 48 as shown below. If you want >36 and <48 it would be 37..47
