[REBOL] [datatypes] action! vs. native! vs function!

From: joel::neely::fedex::com at: 22-Nov-2003 16:15

Hi, all, OK, so a FUNCTION! is a function written in REBOL itself (what FORTH used to call "high-level" in contrast with "primitive"). I've always thought of NATIVE! as "primitive" in the above contrast -- a function written inside the interpreter in C (or whatever), but then ACTION! enters the picture and leaves me scratching my head. Does anyone know the difference between NATIVE! and ACTION! types? -jn-
