站点中还包括很多指向有用的Rexx库的链接，这些库可用于Tk、Curses、SQL等应用程序领域。

Some instructions in Rexx may explicitly specify a stack to operate on ; but other instructions operate within an environment which you configure with the ADDRESS instruction .

Rexx中有一些指令可以显式地指定要操作的栈；但是其他指令操作是在您用ADDRESS指令配置的环境中进行。

Coming more out of an IBM " big-iron " environment than from Unix systems , Rexx is little-known to many Linux programmers and systems administrators .

由于来自IBM“大型机”环境比重多于Unix系统，Rexx对很多Linux程序员和系统管理员是鲜为人知的。

Nowadays ( especially on Linux or BSD-derived OS 's ), most of those older implementations of Rexx are primarily interesting as historical footnotes .

当前（尤其是在Linux或者起源于BSD的OS上），Rexx的那些大部分早期实现，主要作为历史足迹为人们所关心。

Regina is the LGPL Rexx implementation used in writing and testing the examples in this article , and for most people will be the best choice for an environment to install .

Regina是本文编写和测试例子时所用的LGPLRexx实现，并且，对大多数人来说，它是安装环境的最好选择。

And Rexx is certainly Turing-complete , enables modules and structured programming , and has libraries for tasks such as GUI interfaces , network programming , and database access .

并且，Rexx当然是完全Turing的，支持模块和结构化编程，有面向专门任务的库，例如GUI接口、网络编程和数据库访问。

Not every string is valid Rexx symbol which restricts the keys in the dictionary but Rexx is pretty liberal about its symbol names , compared to most languages . E.g.

不是每一个字符串都是合法的Rexx符号为限制程序库中的关键字但是相对于大部分语言，Rexx在符号命名方面非常自由。

For quick and easily readable scripts that perform text manipulation on the inputs and outputs of external processes , Rexx is hard to beat , and not hard to learn or install .

作为可以快速且简单易读的脚本，在对外部进程的输入和输出进行文本处理方面，Rexx无懈可击，而且学习和安装也不困难。

Following the example of the execution of the argument cmd , you could write a shell or interactive environment in Rexx ( perhaps running either external utilities or built-in commands , much like bash ) .

按照参数cmd执行的例子，您可以在Rexx中写一个shell或者交互式的环境（或许会运行外部的实用程序或者内置命令，正如同bash）。

In capabilities and programming level , Rexx can be compared most closely to bash plus the GNU text utilities ( throwing in grep and sed for good measure ); or maybe to awk or Perl .

在实际能力和编程级别上，Rexx最接近于bash加上GNU文件工具（外加grep和sed）；或者可能相当于awk或Perl。

Stylistically , the IBM / mainframe roots of Rexx show in its case-insensitive commands ; and to a lesser degree in the relative sparsity of punctuation it uses ( preferring keywords to symbols ) .

在文体上，Rexx的IBM/mainframe根源体现在它对命令的大小写敏感；在某种次要程度上也体现在它使用标点符号相对较少（更多用关键字而不是符号）。
