HP50G - Viewing .txt Files on SD Card without CR Characters

[BruceH]

It's because you're using DOS format files which use carriage return plus linefeed to denote the end of line.

If you switch to Unix format (linefeed only) then the file appears without the square blobs at the end of each line.

Your editor might have the option to use Unix format otherwise there are many DOS2UNIX type programs that will do the conversion for you.
