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			`: '?

Remove LIT< in favor of LIT" exclusively This duplicated feature existed because of bootstrapping issues with LIT", but again, with careful threading, we can clean things up. We can now have a proper "Collapse OS" prompt :) 2020-09-20 08:51:29 +10:00			`: ' '? NOT IF (wnf) THEN ;`
