Jesper

Thank you so much!! I implemented your suggestion and it gave
me a column number on my mode line that indeed updates itself
as I move around my document!!!

Can I ask you one last question? I noticed that often
the column number will *not* be updated with this
suggestion.  For some reason, on some
lines, the column number is not updated when I move right and
left with the cursor until some event forces an update.
For example, when I change
line numbers that seems to force an update of the column number.
Often pressing right/left arrow *does* effect an update of
column number on modeline but not always.

Thanks again,

Chris
