SteelBlue is an Open Source Web application server similar to Cold Fusion. It extends HTML with tags to execute SQL commands, perform type checking on user input, loop over sections of code, and manipulate data. In addition, it has a Perl-like scripting language that can be embedded directly into the HTML for complex data manipulation. SteelBlue runs as a CGI script on Linux, UNIX variants (via gcc 2.8), and Win32. It includes native support for most popular relational databases and the embedded scripting language is extensible though a C++ API. Included in the distribution are a book about programming SteelBlue, many examples, and a full bulletin board application.
Yabasic implements the most common and simple elements of the basic language. It comes with goto/gosub, with various loops, with user defined subroutines and libraries. Yabasic does monochrome line graphics and printing. Yabasic runs under Unix and Windows, it is small (around 200KB) and free.
Perl is a high-level, general-purpose programming language that makes easy things easy and hard things possible. It is optimized for scanning arbitrary text files and system administration. It has built-in extended regular expression matching and replacement, a dataflow mechanism to improve security with setuid scripts and is extensible via modules that can interface to C libraries.
