Hi. > ..but not sacrifying compactness
Here is what you can do with NO vm kernel word at all: http://mecrisp.sourceforge.net/ ..standalone native code Forth for MSP430 microcontroller chips... ..It fits tightly into 9kb of Flash and runs with 512 Bytes of Ram... By the way, its free. Use whatever routine you like, a great pit. A good job Matthias did there - no not Trute, is Koch this time. :-) Good luck!
