我承认我有点作弊了。我当时是用威廉·F·卢伯特的《What's Where in the Apple II》去 ROM 里找契合我需求的例程。大家可以在这儿下载：http://apple2scans.net/apple-ii/whats-where-in-the-apple/
I confess I kind of cheated. I used William F. Luebbert's "What's Where in the Apple II" to find routines in ROM suitable to what I wanted to do. You can grab yours at http://apple2scans.net/apple-ii/whats-where-in-the-apple/
