After a lifetime writing Ruby, it's frankly kind of surreal seeing something from 1995 using respondsTo methods to decide how to pass messages at runtime. Feels far more modern than I associate with the time.

on mGetFirstFrame me, aTrack
  put the pXObj of me into myXObj
  if myXObj(mRespondsTo, "mGetFirstFrame") = 0 then
    return 0
  else
    return  myXObj(mGetFirstFrame, aTrack)
  end if
end

on mGetLastFrame me, aTrack
  put the pXObj of me into myXObj
  if myXObj(mRespondsTo, "mGetLastFrame") = 0 then
    return 0
  else
    return  myXObj(mGetLastFrame, aTrack)
  end if
end
