The following works for me:
%s/$/\=line('.') % 100 ? "" : " (CHECKED)"/
explanation:
% - for all lines
s/$ - change the end of the line
/\= - to the expression:
line('.') % 100 - will be 0 on lines divisible by 100
? "" - no change (when not 0)
: " (CHECKED)" - change (when 0)
Might be a nicer way to do it, but the:
(condition) ? "" : "something"
expression is pretty flexible.
