Thank you for your response Srinivas. This i tried it before. But it can only scan136th line but i need to scan till 141th line and that too we dont know in which line extracting data present but we know what data we need to extract
The below is the lines we need to extract data from text file. I think search scan might be helpfull but i dont know how to use it. Any help would be greatly appreciated. Thank you in advance
