Why not write your own version of ReadLn that uses ASCII 10 as the delimiter? If you do your own, you might as well write it so that it works on either CRLF, or LF, or LFCR combinations. To keep it simple, start with ASCII 10 as the break character. The only thing that makes ReadLn fast compared to Read one character as a time is that ReadLn uses a good sized buffer. Your version of ReadLn just reads from the buffer and when you reach the end of the buffer, you reload the buffer from the file. If you have the Delphi source for the TextFile routines, you could just make a copy of the source, change the names that would conflict with the TextFile routines and compile. You will also want to implement EOF. Just ask the list if you run into problems in the implementation. Glenn Lawler www.incodesystems.com
