Make string length-prefixed instead of null-terminated I'm not sure why I chose null-terminated initially. Probably because the z80asm version had null-terminated strings. Length-prefixes strings are the traditional form of strings in Forth and it's a bit easier to work with them with traditional forth words when they're under this form. 2020-05-26 10:34:52 +10:00			`: _ ( a+1 len -- n f )`

Move Cross-compiled core from B390 to B350 and renamed it "Core words". Also, reworded the presentation. 2020-05-16 12:44:49 +10:00			`- SWAP EXIT ( 0-n f )`
