  Syntax                    Description
  WIDTH [columns][,lines]   Sets the number of columns and lines to
                            display on the screen.
 
                            The value of columns must be either 40 or
                            80. The default value is 80.
 
                            The value of lines may be 25, 30, 43, 50,
                            or 60, depending on the display adapter
                            used and the screen mode (see the SCREEN
                            statement help topic for more information).
                            The number of lines displayed when the program
                            started will determine the default value.
 
  WIDTH #filenumber,width   Sets the line width of an output device opened
                            as a file (for example, LPT1: or CONS:).
 
                            The filenumber argument is the number
                            associated with the file in the OPEN
                            statement.
 
                            This form permits altering the width while
                            a file is open, since the statement takes
                            place immediately.
 
  WIDTH device,width        Sets the line width of device (a device file
                            name).
 
                            The device should be a string expression
                            (for example, "CONS:").
 
                            Note that this width assignment is deferred
                            until the next OPEN statement affecting the
                            device; the assignment does not affect output
                            for an already open file.
 
  WIDTH LPRINT width        Sets to width the line width of the line
                            printer, for use by subsequent LPRINT
                            statements.
