This attribute specifies the number of columns (number of character cells) that will fit across PRINTER widget WIDTH. See INTERDEPENDENT ATTRIBUTES for details on how ROWS, HEIGHT, COLUMNS, WIDTH, and FONT interact.
If a text line in PRINTER is longer than is specified by this attribute and the value of LINE WRAP is 0, a horizontal scrollbar appears. If the value of LINE WRAP is 1 and there are more characters than specified, the lines wrap around on character cell-boundaries. If a vertical scrollbar is displayed, it consumes some of the COLUMNS space.
