在哪里可以找到 J 中所有运算符的列表
我正在尝试学习 J,但遇到的一个大问题是我不知道所有预定义运算符是什么或在哪里可以找到它们。我花了太长时间才弄清楚|都是余数函数(当它是二元时),但是当它使用一元时,它会获得绝对值或大小。有谁知道在哪里可以找到 J 默认定义的所有运算符的列表?
I am trying to learn J and one huge problem I'm running into is I don't know what all the predefined operators are or where to find them. It took me way too long to figure out the | is both the remainder function(when it dyadic) but when its used monadic it gets absolute value or magnitude. Does any one know where a list of all the operators that J defines by default could be found?

您可能正在寻找 J Vocabulary,尽管尝试阅读其文档一元与二元

对我来说是希腊语。 (免责声明:我不是 J 程序员)You may be looking for the J Vocabulary, although trying to read its documentation on monadic vs. dyadic

is greek to me. (Disclaimer: I am not a J programmer)在 J 版本 6 IDE 中,control-F1 将显示光标处单词的文档(如果在实现中定义了该单词)。希望新的版本 7 界面最终能够保留此功能。
In the J version 6 IDE, control-F1 will bring up documentation on the word at the cursor, if it's defined in the implementation. Hopefully the new version 7 interfaces will eventually manage to retain this feature.
