Is this supposed to happen?
« on: March 23, 2011, 06:14:45 am »
Okay, I made this code:
Code: [Select]
#include "ti83plus.inc"
.org 40339
.db $BB,$6D
B_CALL _ClrLCDFull
B_CALL _BufClr
B_CALL _getKey
ret
It turns off the calc, is this supposed to happen?

The origin looks weird to me, but still
Does it turn the screen off? Do you get a RAM-clear or anything?

nothing else, only hooks are turned off ( homerun hook of DCS doesnt work until you restart DCS). I dont get any error message

EDIT: It has to do with
Code: [Select]
B_CALL _BufClr

yes, it only reacts on [On], not on any other keypress

You will want B_Call _ClrLCDFull. _BufClr clears 768 bytes of memory depending on where the pointer points it to. :D

No, but I am pretty sure there is a GrBufClr or something of that nature. The reason this was include was because the code probably looked something like this:
Code: [Select]
GrBufClr:
 ld hl,plotSScreen
BufClr:
 <<code>>
So it will smaller and the same speed to do bcall(_GrBufClr) than to do ld hl,plotSScreen \ bcall(_BufClr)

You never initialize HL anywhere in your code. But yeah, use grBufClr or write your own quick routine to clear plotSScreen.
