(4,226*) in parenthesis means Column 4 and Line 226, the * star shows you that the file was modified since the last Save.
The "Par" (german "Abs") number counts the Hard Returns up to the cursor position, dot commands are also counted. In unformatted files, the line number in parenthesis is dependent on the current formatting, so the "Par" number is the only useful orientation you will have in unformatted files! With the "Paragraph Dialog" ^QH you can jump to a specific paragraph number.
In Write&Set formatted files (FMT files), an additional "P" and "L" number (Page, Line) is shown like Wordstar does (german "S" and "Z"). These values depend on the page formatting dot commands.
Then, the filename is shown.
If the column block mode (^KN) is activated, "COLUMN" is shown.
If column block is activated and exclusively numbers are
marked, you will see the sum of all numbers in the title bar: ^U = [Sum] and the
sum is copied into the trash buffer.
