52The ''CLINE'' command is used to clear the line currently occupied by the text
53cursor. If ''CLINE'' is followed by a number, then that number of characters
54get cleared, starting from the current cursor position and leaving the cursor
55exactly where it is.

59Il comando ''CLINE'' viene utilizzato per cancellare la riga attualmente
60occupata dal cursore. Se ''CLINE'' è seguito da un numero, quel numero
61di caratteri sarà cancellato, a partire dalla posizione corrente del
62cursore e lasciando il cursore esattamente dove si trova.
