Virgil Dupras	2d17b4e8ec	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.	2020-05-25 20:34:52 -04:00
Virgil Dupras	dfe474ca0e	xcomp: add XCOMPILE and X[COMPILE] ... This allows us to move words like ABORT" to xcomp-core, which is I think the last roadblock before being able to unify all drivers into a single xcomp layer.	2020-05-12 21:08:18 -04:00
Virgil Dupras	1094ec9c57	Make DO..LOOP stable ... DO and LOOP now only compile words from stable ABI, which make them suitable for xcomp. This will greatly simplify driver writing and allow us to mostly avoid the low/high divide in drivers. LEAVE is still xcomp-incompatible though. This make us very very tight for "<0x100" limit for literal words. Hopefully, we won't need more stuff in that area of the binary...	2020-05-12 10:40:59 -04:00
