From CodeGuru.com: This article reads like an advertisement; however, because I believe many of you will find this tool interesting and because source code is provided, I have chosen to post it.

Delta Forth .NET - World's first Forth compiler for the .NET platform

Delta Forth is a non-standard Forth dialect. It has several limitations over traditional standards; however it may be an excellent starting point for beginners. The traditional compreter (compiler interpreter) approach of other implementations did not appeal when the Delta dialect was designed since computers evolved enormously since the original Forth specification was written. Instead, we deal with compiled programs and thus several original Forth words mainly related to chained execution - have lost their meaning (see STATE, COMPILE, IMMEDIATE, etc.).

It has been stated that a complete traditional Forth environment can be coded by a single person in a three month time. I managed to release the beta 1 version of Delta in half that time. Despite the short time it took to be developed, this tool has a long history, being a continuation of the award-winning Delta Forth for Java project that I started back in 1997. At that time, it was the first Forth compiler for Java and was a real surprise when I presented it as my graduation project two years later. The .NET compiler is used to write a part of the software for my Ph.D. thesis.

This software is free of charge. However, I spent hundreds of hours designing and developing it, so if you like it please make a donation to a charity of your choice then drop me a note.
