Mr.Pelc woke us all up to the NG comp.lang.forth.
Just been browsing there, and anyone needing an excuse to NOT use FORTH just needs to browse there to discover that the world of FORTH is a complete mess of incompatible versions.
It would seem that for every programmer asserting himself as a FORTH expert, there is yet another version of FORTH!
With my professional (now retired) hat on, FORTH is a joke in the world of educated computer professionals, but with my amateur hat on, it is great fun to dabble with implementations of interpreters, whether tokenised, lists of addresses, or blocks ofsubroutine calls, and for the latter, in the case of the RPi, for most primitives there's no need to save R30 (in 64 bit mode) when called by BL!
