  It's easy. Write something like this at the beginning of the scene:

#if(clock=0)
  // set initial values to the persistent variables
#else
  #fopen iFile "variables.dat" read
  // read values for persistent variables from iFile
  #fclose iFile
#end

  At the end of the scene:

#fopen oFile "variables.dat" write
// write values of persistent values to oFile separated with commas
#fclose oFile

  I have used this method in my 'robots' irtc animation with success.
