FILL [kette]This command is filling up records by moving so many words from the following record into the the current record as may have place in the visible line (value of LWWIDTH). The same action takes place for the next record and so on.
Filling up always starts with the current line.
Filling stops either before the next blank line or before that record which begins with string, or at the end of the file. If you do not specify a parameter then the stop record will be the next blank line.
If you have a text where paragraphs are marked by blank lines or by an unambigious mark at the end of the paragraph (but at the beginning of a record), you may by this means fill the text paragraph by paragraph. In all cases you should make sure that the blank lines or the stop strings are present or are typed in the right way. Otherwise the filling up may unwantedly run too far or even to the end of the file.
