  Perhaps a few people knowing about TextEdit could help here.  I have a few
questions about the lineStarts and nLines fields.

(1) When you first initialize a TextEdit field? what are the values of
    these three fields?  I assume nLines is zero and lineStarts
    is completely uninitialized.

(2) If I then enter an X into TE through TEKey, what are the values of the
    two fields?  I assume lineStarts[0] = 0.  What would nLines and 
    lineStarts[1] would be?

(3) I then enter a \r, so the record contains X\r.  Now I get lost.  Is
    nLines 1 or 2?  lineStarts[0] = 0.  Does lineStarts[1] = 1 or 2?  Are
    all other values of lineStarts uninitialized?

(4) If I then enter a Y, so the record contains X\rY, what is the value of
    nLines?  lineStarts[0] = 0.  What is lineStarts[1]?  Is lineStarts[2]
    defined?

In another unrelated question.  I have found out that TextEdit displays
actual CRs at the end of each line when it is displaying a record.  I wish
to use a character set where very character is printable.  Is there any way 
to have TE do the proper line ends, without actually putting a CR on the 
screen?  (I would display Chr(13)'s using another routine that wouldn't 
use TE when the user wanted that character printed)

    Thanks for all the help.  If you wish to e-mail rather than post, I can
