Re: How add one to column # on modeline (%c) so starts from _1_?

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????
