Last week I released the 27th release of the this Small Forth for simple µCs (by today's standards - what's "simple" today would have been the stuff of dreams in the 1990s).
STM8 eForth 2.2.27 contains nifty features, e.g. an easy to use "compiler overlay" for structure words (e.g. IF ... ELSE ... THEN) with relative branches. This is useful for e.g. for the ISR programming or for relocatable code. Mixing Forth code with assembler instructions is now an really easy thing to do.
That 40 years old bug in UM/MOD I wrote about the other day: it's been fixed now, but it almost deserves a place in a museum of computer history!
