> I'm sorry if my stupid question was annoyed you.I didn't think your question was stupid. Stupid was (a) CP/M recording file size as number of 128-byte sectors, forcing the use of an in-band EOF marker for text files (b) MS continuing to regard Ctrl-Z as an EOF decades after people stopped writing Ctrl-Z at the end of text files. And I wasn't annoyed either ... I was merely adding the information that Ctrl-Z and '\x1a' were the same thing; many people don't make the connection.
