old threaded languages, was Re: Symbolics

Someone wrote... The first OS type design project I was ever offered was to write a run time forth interpreter and complete OS environment for it on Microdata Reality computers (subsequently McDonnell Douglas Computer Systems). As I recall they had some type of medical oriented accounting or business package written in forth and they wanted to make it run (without another underlying OS) on the Reality platform (which they owned). They offered me almost triple what I was currently making to be the lead engineer on the project. I was absolutely salivating at the thought of doing a complete OS design from scratch, but in subsequent interviews it was obvious to me that they would likely let me go once the project was written so I didn't take it. I've never touched forth since then. This is almost 20 year old memory cells trying to activate here, but I thought Forth was generally implemented by "compilation" into a non-standard pCode which was then run interpretively by a stack oriented run time engine. Thus, I would have said it was a stack oriented language. But I guess it depends on if you're looking at the language itself or how it is normally executed? Jay West
