It is easy to get lost in the world of "little languages"--quite a
few have been written to scratch some itch of a company, individual
or project. Rexx is one of these languages, with a long history of
use on IBM OS's, and good current implementations for Linux and
other Free Software operating systsems. Moreover, David argues that
Rexx occupies a useful ecological niche between the relative
crudeness of shell scripting and the cumbersome formality of full
systems languages. Many Linux programmers and systems
administrators would benefit from adding a Rexx implementation to
their collection of go-to tools.
