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. 2020-06-11 18:12:01 -04:00			`CREATE PREVPOS 0 , CREATE PREVBLK 0 ,`
Remove MIN and MAX from core It isn't used in there anymore. Moved it to VE, the only place where it's used. 2020-11-08 17:22:54 -05:00			`: MIN ( n n - n ) 2DUP > IF SWAP THEN DROP ;`
			`: MAX ( n n - n ) 2DUP < IF SWAP THEN DROP ;`
VE: make ACC reset after each non-digit keystrokes It simplifies things. Also, removed ';' which became useless. 2020-06-10 16:54:36 -04:00			`: acc@ ACC @ 1 MAX ;`

ed: rename I to i Shadowing core "I" is too messy. As soon as ed is loaded in memory, nothing else that isn't "i-aware" can be loaded anymore. I guess that's why "contexts" exist in Starting Forth, but adding this concept just for allowing the shadowing of core words seems overkill to me. Renaming I to i in ed seems better. 2020-06-23 07:08:21 -04:00			`: clrscr LINES 0 DO I aty COLS nspcs LOOP ;`

VE: refactor mode indicators The indicator is going to be empty most of the time and will be emitted by the mode changer directly. That's going to the upper-right corner and the status bar avoids emitting in that area. 2020-06-05 10:38:05 -04:00			`: status 0 aty ." BLK" SPC BLK> ? SPC ACC ?`
