From VOA Learning English, this is the Technology Report.
 
May 1st marked the 50th anniversary of a special computer language. The new code was designed to permit college students not trained in mathematics to use computers.
 
50 years ago, computer owners were mainly governments, businesses and universities. Programmers wrote pages of commands in mathematical expressions to operate these early computers.
 
John Kemeny and Thomas Kurtz were two professors in the mathematics department at Dartmouth College. They wanted students in other departments to be able to use their school's computer. So they developed a simpler set of computer commands called Beginner's All-purpose Symbolic Instruction Code, or BASIC.
 
"We deliberately invented a language that was almost devoid of many of the technical details that were present in other languages," said Kurtz.
 
BASIC puts English commands, such as IF...THEN, or GO...TO, into a numerical language computers can understand. Mr Kurtz says almost everyone at Dartmouth College began using computers.
 
"Not only our students loved getting onto the computer any time they wanted to, for whatever purpose they wanted to, but even the faculty got interested. Of course not everybody, but many of them," Kurtz said.
 
BASIC was a major step toward the development of personal computers. Peggy Kidwell is the Curator of Mathematics at the Smithsonian National Museum of American History. She says BASIC was created just as computers became fast enough to perform many commands at the same time.
 
"Now, that whole notion that anybody could run a computer permeates the whole world. And I would say that is not the immediate legacy of BASIC but it is a part of what was involved in building up on BASIC," said Kidwell.
 
Mr Kurtz and Mr Kemeny released BASIC to the public for free, the computer language quickly became very popular. Mr Kurtz says they hoped the language would solve what they saw as a major upcoming problem.
 
Mr Kurtz says he and Mr Kemeny believed that the computer would become very important in the world. He says most people didn't know anything about computers because they were only used by experts.
 
The speedy development of computers was followed by many improved versions of BASIC. Over the years, code writers created other easy to use computer languages.
 
Today, few people use BASIC, but personal computers owe their existence to the first programming language that anyone could speak.

这里是美国之音慢速英语科技报道。

5月1号标志着某门特殊的计算机语言50周年。设计这种新型编码可以让没学过数学的大学生使用计算机。

50年前,计算机主要用于政府、企业和大学,程序员用数学公式编写好几页命令操作这些早期的计算机。

John Kemeny和Thomas Kurtz是达特茅斯学院数学系的两位教授。他们希望其他系的学生能使用学校的计算机。因此他们研发了一套更简单的计算机命令,被称为“初学者通用符号指令代码”(或 BASIC语言)。

Kurtz 说:“我们特意发明一门语言,不包括任何在其他语言中存在的技术细节。”

BASIC语言将诸如“IF...THEN或 GO...TO”的英语命令转换成一种计算机易懂的数字化语音,Kurtz先生称达特茅斯学院几乎所有人开始使用计算机。

“不仅仅是我们的学生随时使用计算机做任何事情,甚至我们的教员也很感兴趣。当然并非所有人,但是人也不少。”

BASIC语言是个人计算机发展的重大一步。Peggy Kidwell是史密森尼国立美国历史博物馆数学馆馆长,她表示BASIC语言刚好产生于计算机快到可以同时执行多个命令。

“现在,任何人能操作计算机的这种理念蔓延至全球,我想说的是这并非BASIC语言的直接产物,但是它基于BASIC语言所研发的一部分。”

Kurtz先生和Kemeny先生向公众免费发布BASIC语言,该语言好评如潮,Kurtz先生表示他们希望该语言能解决他们认为即将发生的一个重大问题。

Kurtz先生表示他和Kemeny先生相信计算机将在全球变得至关重要。他表示多数人对计算机一无所知是因为计算机的主要用户是专家。

随着计算机飞速发展,多种优化版的BASIC语言诞生了。多年来,程序员创建了其他易于操作的计算机语言。

如今,很少有人使用BASIC语言,但是个人计算机的存在要归功于这一首门任何人都可以使用的编程语言。
