REBOL/Command - For Professional Developers

REBOL/Command is our full strength REBOL implementation for commercial developers, enterprise users, and server-side applications. REBOL/Command extends the features of REBOL by integrating access to database systems, secure environments, Web server interfaces, and legacy applications.


Internet applications must be able to fetch, analyze, modify, and transmit information across the Internet using a wide variety of protocols. The rapid development of these applications requires a powerful and compact system that is easy to learn and extremely flexible. With REBOL/Command based lightweight distributed computing, applications can move information from back-end sources to client destinations across the Internet as easily as if they were running on the same computer.

Includes 14 Internet protocols, 40 datatypes, 350 functions, dialecting, and compression.

REBOL/Command requires no installation. Just run the binary.

Database Access

Direct database access to:

  • Oracle 8 (Windows, Solaris Sparc, and Linux libc6 systems)
  • MySQL 3

ODBC access (from Windows) to:

  • Microsoft Access
  • Microsoft Excel
  • Microsoft SQL Server
  • Oracle
  • MySQL

FastCGI Server Interface

FastCGI provides 5 to 10 times faster REBOL CGI scripting. FastCGI is a standard, secure Web server interface that solves the performance problems inherent in CGI without the overhead and complexity of proprietary APIs.

Secure Socket Layer (SSL)

Client-side Secure Socket Layer (SSL) and Transport Layer Security (TLS) with HTTPS protocol. Includes: SSLv2, SSLv3 and TLSv1with DES, 3DES and ARCFOUR in all strengths. RSA keys and DSA/DH keys are supported.

Encryption Ports

Easy-to-use encryption and decryption methods, including:

  • Symmetric key encryption with Blowfish (576 bits) and Rijndael/AES (256 bits).
  • RSA public key encryption (unlimited key size). Used for session key exchange and electronic document signing.
  • DSA digital signature algorithm (unlimited key size). Used for electronic document signing.
  • DH (Diffie Hellman) key exchange (unlimited key size). Used for session key exchange.

Export restrictions may apply to encryption technology.

REBOL/View Graphics Engine

Server-side access to REBOL's graphical effect pipeline and compositing engine plus draw modes without opening graphics libraries (e.g. X-windows). Order Command now and receive a free copy of Command/View which adds all of the features of REBOL/View.

External Library Access

Interface to legacy systems or directly execute standard operating system dynamic library functions. Or, use it to extend REBOL's functionality at the 'C' code level by creating your own native libraries. Shell Application Access

Call external applications and utilities directly from REBOL through your system shell interface. Launch applications or an entire job stream, pass control information and parameters, and collect results for further REBOL processing. Easy Installation


What Customers Say

"REBOL/Command has done a great job. We bought the system and within two hours we were distributing a database across multiple systems to integrate with XML and HTML. Our development time and costs are dramatically reduced, thanks to Command, enabling us to invest our time into more innovative tasks. REBOL/Command has proved to be of substantial value to our company."

--Maarten Koopmans, Senior Technology Consultant
