This control sets the number of characters per line that are printed on the output listing. Characters past this position are ignored. This is also used as the position to which the page number and date are aligned in the header. Values between 64 and 255 can be specified. Although some terminals are 80 characters wide, writing a CR-LF in the 80th spot causes a subsequent blank line to appear. In this case, you should use 79 as the width. The default is 79 and the class is primary.
