A86: TI-86 Direct Input!

Hello Everyone,

	I had an 86 for sometime, but didn't have the courage to start z80 on it
till today.  I do know z80, I have an 83, and I made a Periodic Table for
the 83.  Yet I decided to try to convert it to the 86, it is all text, and
I will release it after I find the answer to one question.  The question is
at the bottom.  Anyway, the TI-86 does use the same Direct Input keys as
the 83, at least for some things.  It worked for me on Chem.  What is
direct input ?  Tell the calc the row of the key, then it looks for it in
that row.  Here is an example :


------------------------------------------------

#include "asm86.h"         ;this header file *must* be before ti86asm.inc
#include "ti86asm.inc"

.org _asm_exec_ram     

init:
	call	_clrLCD
	ld	hl,15*256+0
	ld	(_penCol),hl
	ld	hl,presskey
	call	_vputs

GetKeyLoop:
       ld      a,0ffh          ; Reset the keyport 
       out     (1),a	     
       ld      a,0fdh          ; Enable the row with clear
	out	(1),a
	in	a,(1)		
       cp      191             ; Check for clear
       jp      nz,GetKeyLoop
	jp	z,quit

quit:
	call	_clrLCD
	ret

presskey:
	.db	"Press Clear to Continue!",0
.end
END

-----------------------------------------------------------


So that is that.  Anyway, for the codes, etc, goto the TI-Files or my page
(http://ahmed1.home.ml.org), and read my TI-83 ASM Journal (I mean 83, not
86) under the TI-83 Docs/Info section, I think it is the second or 3rd, and
the last one probably has it as well.  Just wanted to share that.  Now for
my question(s):


1. To finish Periodic Table, how do you turn RunIndicator Off ?  I tried
call BUSY_OFF, but I get a syntax error with Tasm (I use Alan's ASM86 2.0).
 Is there a define or something I forgot ?

2. How do you convert a pcx to asm ?  There is a program to do it for the
83, but I want to know how to do it for the 86.

3. What is the 86 equivelent of (_grbufclr)?  And is it possible to get a
picture from 86 vars out by recalling it w/a basic program and then doing
the equivelent of (_grbufcpy_v  aka. Copy Graph Buffer) ?

Thanks.  If you can answer any of these, please do!
