Thanks for the tip, i'll implement that in my future codes, i don't know this can be possible. Also, for this piece of code is not necessary,because i only need to do that once a month as a scheduled task on a 8cpu SCSI RAID drives server (i dont care if this takes a lot of time, this server has this time to waste :) ) Also, i fix this problem using another aproximation: If i found condition 6, it write condition 6 and 7, and when i found condition 7, i trash it, because i wrote a cycle before. Smart, isnt? :) Thanks for all indeed, now i have another weird case with quotes. Im gonna open a new post.
