一、概述在微机的操作系统中,一般都有发出固定频率声音的功能,例如,当出现错误信息时能自动发出铃声。然而,在不少微机(比如使用较广泛的APPLEⅡ型微机)中没有演奏音乐的系统软件,要使它演奏音乐,必须由用户设计并输入应用软件。笔者经过一段时间的试验,已经编写出比较完整的“音乐程序”软件,在APPLEⅡ型微机上使用,效果良好。本程序用BASIC语言编写,程序执行过程中在显示器上列出操作说明,使用起来十分简单方便。对于初学微机者或少年儿童,只要花费很短时间熟悉键盘操作方法,就可通过微机获得各种乐曲的数据资料,并演奏出悦耳的音乐。
First, an overview In microcomputer operating system, usually have a fixed frequency sound function, for example, when an error message can automatically ring. However, system software that does not perform music on many computers (such as the widely used microcomputer APPLE II) must be designed and input by the user for the application to be played. After a period of trial, the author has compiled a relatively complete “music program” software, used in the APPLE Ⅱ microcomputer, the effect is good. The program written in BASIC language, the program execution process listed in the display operating instructions, it is very easy to use. For beginners or young children, as long as you spend a very short time familiar with the keyboard operation, you can get a variety of songs through the computer data and play music.
