While you can solve many problems easily by stringing together existing utilities, solving other problems requires at least some amount of real programming.
虽然能够通过结合使用现有实用程序来容易地解决许多问题，然而解决其他问题却至少需要一些实际的编程工作。
For example, a product group might identify three main types of reference topic — messages, utilities, and APIs — and define three domains — networking, programming, and databases.
例如，产品组可能将引用主题标识为三个主要类型：信息、实用程序和API。
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。
