Virgil Dupras 1e7e696e4a forth: Forth-ify ";"!!! 
Ain't that not self-bootstrapping enough to your taste? Whoa, I'm
getting dizzy...
 2020-03-27 09:32:03 -04:00
Virgil Dupras dad0081123 forth: Forth-ify "INTERPRET"!!! 
Now we're seriously getting into real boostrapping territory...
 2020-03-27 08:23:45 -04:00
Virgil Dupras cb3e6469b8 forth: make "(parsed)" support negative literals 
This limitation was becoming annoying...
 2020-03-26 14:47:17 -04:00
Virgil Dupras 40eda1d933 forth: Forth-ify "*" 2020-03-26 14:36:14 -04:00

binaries.

Virgil Dupras 42abbe75aa forth: remove 0 and 1 constants 
They do save space (nearly 100b), but they complicate our Forth-ification
process. We'll re-add them later.
 2020-03-26 11:05:58 -04:00
Virgil Dupras 6eaabb9bbe forth: make word name of variable length 
This allows us to save a whole 500 bytes on the final binary size!

This change comes after I took a look at the hex dump and saw that one letter
constants in z80a.fs took a lot of space.
 2020-03-26 10:53:33 -04:00
Virgil Dupras 52e6eaafc7 forth: Forth-ify "/MOD" 2020-03-25 22:51:23 -04:00
Virgil Dupras 61bb22e8c9 forth: straighten out "/MOD" 
The removal of the "divide" routine highlighted the fact that
nativeWord wasn't properly stabilized.

Virgil Dupras d6516e2122 forth: Forth-ify "2*" stack management words 2020-03-24 14:44:10 -04:00
Virgil Dupras 67c55b0b2f forth: Forth-ify ROT, a native word! 
This requires us to significantly adjust our build process, which
now has 3 stages.
 2020-03-24 13:46:05 -04:00
Virgil Dupras ca7c21d49f forth: make "(entry)" call WORD itself 
Otherwise, when a defining word would be called outside a definition
itself, it would get the name of the last parsed word, that is,
itself!

For example, dummy.fs, instead of creating a "_______" entry, created
a "(entry)" entry...
 2020-03-22 22:27:54 -04:00
Virgil Dupras 5387e08437 forth: make bin staging process a bit less hackish 
The goal being to add a new native code dict staging phase.
 2020-03-22 21:46:43 -04:00
Virgil Dupras ffe61a12f8 forth: make prev word field relative
