While at work I do a little C and Pearl. When working on home projects I pull out some Forth. As an example: Once I have the template, I write an assembler in an evening. As Mike has shown, it is a "Do it as you see it" type language. This makes debug a snap and eliminates most of those hidden precedence order bugs that seem to sneak into code. It is a type-less language so you have to be a big boy and know that you can't multiply a character times 5 and get a meaningful result. In general it is a vary structured and modular language that allows the language to be expanded to be the solution. The bad part about Forth is dealing with all of the stack manipulation words. Many consider them to be unnecessary noise. Still, one can get Forth running on most processors with a minimum of time and effort. You start with a minimal interpreter/compiler that runs from a terminal and build the rest on the machine in question. No need for ROM-ICE or special debuggers. Dwight
