The
Amiga version of Rexx is called (unsurprisingly)
ARexx, and due to
Commodore including it with
Workbench since 1991, has gained amazing popularity.
Nearly every Amiga program has an ARexx port, and with a small bit of scripting can be asked to communicate with any other ARexx capable program. Most Amiga web servers, including Apache, can use ARexx for CGI programs, and this opens up almost infinite possibilities for Amiga-hosted web sites.
