How does one have a line without an end to the line? I always assumed that all lines ended with <LF>, including the last line of the file.... I can conjecture the creation of text at the end of the file without a <LF> at their end, but that to me is not really a line. I guess I fall back to more of a read loop, I suppose.... Of course, this is the beauty of Unix/Linux: we can each define as we see fit..... --Rob
