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. 2020-05-13 11:08:18 +10:00			`: EMIT`

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			`: (print) C@+ ( a len ) 0 DO C@+ EMIT LOOP DROP ;`

Refer to BOOT and (uflw) by addr in stable ABI Was previously referred to by name+find, which was wasteful. 2020-06-22 01:41:10 +10:00			`XCURRENT @ _xapply ORG @ 0x06 ( stable ABI uflw ) + !`
