汇编 语言

(2003年4月2日补记)

课程的名称为 Introduction to Assembler for the IBM PC，课程代号: COMP1410, 12节课，3个学分。

这门课并没有列在必修课程表里，是我自己选的。那时，自己对电脑很有兴趣，特别是迷上了电脑游戏，对那层出不穷的变化感到很惊讶，赞叹计算机的强大功能。于是想知道计算机的原理到底是怎么样的，这些游戏软件是如何制作的，有股想“打破沙锅问到底”的劲头。听说 Assembler 是最底层的编程语言，便参加了这门课。

现在在 BCIT 大专课程表里见不到这门课了。我以为 BCIT 淘汰了它，学生不用再学了。不料后来发现它被 BCIT 列入计算机本科课程表里去了。

课本 采用老师自编的教材，15元钱。参考书为 Assembler Language for Intel-Based Computers,第3版。

老师 跟教Quick Basic的是同一个老师。

学习工具 可使用Borland Turbo Assembler 5 或 MS Assembler V6.11。
