Page command

    Purpose:  Lists the specified block of lines.

    Format:   [line][,line]P

    Remarks:  If the first line parameter is omitted, it defaults to the
              current line plus one. If the second line parameter is omit-
              ted, 23 lines are listed. The new current line becomes the
              last line displayed with the Page command and is marked with
              an asterisk. This command pages through a file displaying 23
              lines at a time. It differs from the List Lines command in
              that it makes another line the current line.
