TILEforth was designed for 68000 machines, but has been ported since to different platform, among which Linux. Its documentation is pretty good, and it comes with many examples.
TILEforth is a 32-bit implementation of the Forth-83 Standard written in C. Thus allowing it to be easily moved between different computers compared to traditional Forth implementations in assembly.
The implementation of TILEforth is selected so that, in principle, any C-level procedure may become available on the interactive and incremental forth level. Other models of implementation of a threaded interpreter in C are possible but these are not as flexible.
TILEforth is organized as a set of modules to allow the kernel to be used as a general threading engine for C. Environment dependencies such as memory allocation, error handling and input/output have been separated out of the kernel to increase flexibility. The forth application is "just" an example of how to use the kernel.
The kernel supports the Standard Forth-83 word set except for the blocks file word set which are not used. The kernel is extended with many of the concepts from modern programming languages. Here is a list of some of the extensions; argument binding and local variables, queue management, low level compiler words, string functions, floating point numbers, exceptions and multi-tasking. The TILEforth environment also contains a set of reusable source files for high level multi-tasking, data description and structuring modules, and a number of programming tools.
