then goto line 0, and search for the string "=0" through the entire code. since its a filterscript, it wont find that many results. oh, DINI uses the "=" for defining values (like Admin=5), so searching for each "DINI_" line will do a better job. comment some lines out which re-format your saver string, it cant be that hard to spot that bug.
edit: as Wesley221 suggested: stick to the native file functions, you can depend on their efficience.
