Delphi:Delphi在一段文本中查找指定的字符。在下列文本中查找一下“an”试试吧，尽管AssignPrn简化了文本打印操作，使输出到打印机像输出到文件一样简单。但简单带来的是一系列的不方便：你无法知道当前打印的行数，无法准确控制行距，无法灵活改变字体字形等等。还是用打印机的Canvas属性进行打印吧。如果你在编写一个文本编辑功能的小程序，那么查找指定字符可是一个必不可少的功能噢。

-Delphi: Delphi to find the specified character in some text. Find the following text about "an" try it, although AssignPrn simplified text printing operation, the output to the printer as simple as output to a file. But simply to bring a series of inconvenient: you do not know the current number of lines to print, can not accurately control the line spacing, font and so can not be flexible and change the font. Or print it using the printer s Canvas property. If you are writing a text editing features of small programs, then find the specified character but an essential feature Oh.
