   Perhaps something like this might work:

function WhatMyLineEnding DerFile
  # DerFile had better have been read as a binary file;
  # otherwise, Rev will have automagically converted all end-of-line 
characters
  # to whatever is used by *your* machine
  put numToChar (10) into MyLinefeed
  put numToChar (13) into MyReturn

  put the length of DerFile into OldLength

  # how many lines?
  put the number of lines in DerFile into NumOfLines

  # how many linefeeds?
  put DerFile into Fred
  if char -1 of Fred <> MyLinefeed then put 1 into NumOfLFs
  replace MyLinefeed with "" in Fred
  add (OldLength - the length of Fred) to NumOfLFs

  # how many returns?
  put DerFile into Fred
  if char -1 of Fred <> MyReturn then put 1 into NumOfReturns
  replace MyReturn with "" in Fred
  add (OldLength - the length of Fred) to NumOfReturns

  # how many (return+linefeed)s?
  put DerFile into Fred
  if (char -2 to -1 of Fred) <> (MyReturn & MyLinefeed) then put 1 into 
NumOfCRLFs
  replace (MyReturn & MyLinefeed) with "" in Fred
  add (OldLength - the length of Fred) div 2 to NumOfCRLFs

  switch
    case (NumOfCRLFs = NumOfLines)
      put "Win/DOS" into FileSource
    break

    case (NumOfLFs = NumOfLines)
      put "Unix" into FileSource
    break

    case (NumOfReturns = NumOfLines)
      put "Mac" into FileSource
    break

    default
      put "???" into FileSource
  end switch

  return FileSource
end WhatsMyLineEnding

    Hopefully, this handler can identify which flavor of line-endings are 
used in any arbitrary file...
