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????
