FTCBASIC
Homepage: http://lucidapogee.com/index.php?page=ftcbasic
FTCBASIC means fast tiny compiled BASIC. It is a BASIC compiler for x86 DOS. The compiler is written in QuickBasic and generates FASM output. Using batch files, you may compile your source to com files instantly.
Generated com files are tiny and fast. They start at less than 50 bytes.
The compiler and language is derived from the Pebble language. Many of the great features of Pebble have been kept in translation. As a result, there's support for inline asm, include files, and more. There's even some basic 1D array and string data type support.
In all, there's integer, integer array, and string data types. Floating point is not supported, but may be implemented with libraries.
Only unsigned integers may be used in expressions. Operator precedence is *, /, +, -, <, >, <=, >=, =, <>, AND, and OR. Parenthesis override operator precedence.
** Notice: This Alpha version is fresh off the press and probably has issues. Also, the documentation is incomplete. I will be working on it, but wanted to make an early release to get some feedback. **
