Then check if the line count exceeds the page length. 然后检查行的总数是否超过页长。
This was chosen as the default as it is a very common page length on line printers. 选择72作为缺省值是因为在行打印机上这是很常见的页长度。
This sets the page length to66 lines, so selpg will treat the input as though it is demarcated into pages of that length. 该命令将页长设置为66行,这样selpg就可以把输入当作被定界为该长度的页那样处理。
Margins can be established; page length can be defined; and many other functions that involve the manipulation of the written word can be performed. 可以建立页的边缘空白;可定义页长;其他凡涉及对字处理的功能都能够执行。
Selpg keeps track of the current page number as follows : If input is fixed-lines-per-page, it counts newlines until the page length is reached and increments a page counter. selpg通过以下方法记住当前页号:如果输入是每页行数固定的,则selpg统计新行数,直到达到页长度后增加页计数器。
