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			`: '?

VE: add 't' This is the first commit I do entirely in VE. It's a habit I'm planning on taking as it helps a lot to find usability issues. 2020-06-12 08:12:01 +10:00
