Writes to the file or device that is associated with the path number specified.
Write Line is similar to Write. The difference is that Write Line writes data until it encounters a carriage return character. It also activates line editing for character-oriented devices, such as terminals and printers. The line editing refers to auto line feed, null padding at the end of the line, backspacing, line deleting, and so on.
Before using Write Line, be sure the path opened or created in the write or update access mode.
For more information about line editing, see “SCF Line Editing Functions” in Chapter 6.
