Make KEY and EMIT into switch words 2020-10-29 07:00:58 +11:00			`SYSVARS 0x53 + :** 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 ;`
Move a bunch of words from XPACKed core to xcomp core 2020-05-14 21:58:55 +10:00			`: BS 8 EMIT ; : LF 10 EMIT ; : CR 13 EMIT ;`

Use SYSVARS instead of RAM+ in core switches defs RAM+ is the host's setup! Use SYSVARS instead, which is the guest's value. 2020-10-29 06:47:49 +11:00			`SYSVARS 0x0a + :** NL`

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 ) + !`

Move EMIT to low core This allows us to remove one layer of indirection in (wnf). This is possible now that EMIT is a switch word. 2020-10-29 07:34:49 +11:00			`: (wnf) (print) LIT" word not found" ERR ;`
