%c on modeline gives column number but it
starts at 0 which is silly...
How add 1 to this so starts at 1???
(%c + 1) doesn't do it of course.

Try the (:eval FORM) construct.

Thanks for this tip!
I read Emacs Lisp manual on this and followed the example.
After some tweaking I can get eval to print something without
an error by adding following to modeline list....
'(:eval "%c + 1")
The ' and the double quotes are necessary.
The above will print "0 + 1" on the modeline when in the first column.
*****How can I tell Emacs to evaluate the *addition* in quotes rather
than just interpret it as a /string/????

This is because it thre result is a string which contains those characters.
What you need to do is
o convert %c to an int - (string-to-int "%c")
o add one to this value - (+ (string-to-int "%c") 1)
o Return the result as a string (format "%s" (+ (string-to-int "%c") 1))

Thus try
(:eval (format "%s" (+ (string-to-int "%c") 1)))
And don't forget to use column-number-mode!

Thanks for the help!!!!!
I implemented your suggestion in my mode line def....
(setq default-mode-line-format (list ""
'mode-line-buffer-identification
" "
(system-name)
" "
'(:eval (format "%s" (+ (string-to-int "%c") 1)))
"Line %l Col %c"))
Indeed the eval part delivers a "1". The problem is that the "1" is
not updated as columnn number changes.... it just stays "1" for all
time....
What did you mean by "column-number-mode"??? Perhaps that would
solve problem of updating the eval line continuously????

It's generally a good idea to be clear about the "big picture"
surrounding the issue at hand. I'm not sure what it is in this case,
but I'm guessing that you're wanting the modeline to show the column
number of the cursor (in emacs-speak: the "point"). It might also be
wagered that this is more for the sake of intellectual curiosity.
If the goal is the first, you could put this in your ~/.emacs:
; set line numbering on
(setq-default line-number-mode t)
If the goal is more the second, you might want to have a look at the
elisp source now and again as you compose your code.
hth,
