There has been quite a discussion about this, and some time back someone posted
a script reported to do this, which I don't have.  It seems to me it is a bit
more complicated than what is mentioned above because the number of lines
in the field does not necessarily correspond to the number of displayed lines
if lines auto-wrap (no 'return' at the end of the display line).  You would
actually need to compute the width of a line relative to the width of the field
and count the number of display lines the field line occupies.  Is this right?
This is the part I am uncertain of how to do.

Could someone E-Mail me the previously posted script if it does this.

Thanks,


John G.
