View source for Chinese BASIC

'''Chinese BASIC''' ({{zh|c=中文培基|p=Zhōngwén Péijī}}) is the name given to several [[Social:Chinese language|Chinese]]-localized versions of the [[BASIC]] [[Programming language|programming language]] in the early 1980s.
== Versions ==
At least two versions of Chinese BASIC were modified [[Software:Applesoft BASIC|Applesoft BASIC]] that accepted Chinese commands and variables. They were built into some Taiwan-made Apple II clones. One of these was shipped with the best-selling Multitech [[Engineering:Microprofessor II|Microprofessor II]] (known as [[Company:Acer Inc.|Acer]] today). Another version was shipped with MiTAC's Little Intelligent Computer ({{lang|zh|小神通}}).<ref>[https://web.archive.org/web/20060503220144/http://www.apple2clones.com/?q=image%2Ftid%2F91 http://www.apple2clones.com/?q=image/tid/91]</ref>

In addition to Apple II clones, Multitech also developed a Zilog Z80-based port of the Chinese BASIC for its own line of high-end computers.

== Example ==
In a typical Chinese BASIC environment, Chinese and English commands are interchangeable. It may also accept Chinese and Latin alphabet variables. For example, you may use {{mono|PRINT A}} in line 50, {{mono|印 A}} in line 200 and {{mono|? A}} in line 250. They all do the same thing—to print out the value of {{mono|A}} on screen.

This program calculates the sum of {{math|log (''E'') + log (''E''+1) + log (''E''+2) + ... + log (''F'')}}. The [[Social:Chinese characters|Chinese characters]] used as variables are the 24 radicals of the Cangjie method, one of the earliest [[Engineering:QWERTY|QWERTY]] keyboard-compatible Chinese input methods. 

The significant length of an Applesoft BASIC variable name is restricted to two [[Byte|byte]]s. Therefore, the variables {{mono|THISNUMBER}} and {{mono|THATNUMBER}} are treated as the same. In Multitech's Chinese BASIC, a variable can be 3 bytes long (one Chinese character + one numeral).
