Quote from: Lesson 7 Page 11
T-States: Byte Storage:
JR—12 if condition is true 2 Bytes
7 if condition is true 2 Bytes
JP – 10 no matter what
Which is it 12 or 7 if the condition is true?
Which one is it if it is false?

Oops: 7 T-States if condition is false

#include “ti83plus.inc”
.org 40339
.db t2ByteTok, tAsmCmp
B_CALL _ClrLCDFull
ld a, 1
cp 1 ; If A = 1
jr z, DisplayNumber1 ; A – 1 = 0. So, if A = 1, CP 1 will
; give A – 1 = 1 – 1 = 0, therefore the
; zero (Z) flag will be set
cp 2
ret z ; If A = 2, end the program
DisplayNumber1:
ld h, 0
ld l, a ; Remember that CP does not affect A. A still equals 1.
B_CALL _DispHL
B_CALL _getKey
B_CALL _ClrCLDFull
ret
I think should be B_CALL _ClrLCDFull

Yeah, you're right, and that one's weird because I usually test my programs

I don't think it is the equivalent of "If A = 1".

Did you mean "inc hl"?

This too:

Text:
.db “Hello World”, “This is my string,” 224, 65, 67, 67, 65, etc.

This one is really knit picky.

I don't know what is wrong with the second one, but definitely inc hl instead of inc h.

For the second one, I thought it should be
.db "Hello World", "This is my string", 224, 65, 67, 67, 65, etc.

In the lesson, it was:
Quote
.db "Hello World", "This is my string," 224, 65, 67, 67, 65, etc.

I don't know. I am supposed to be the one learning.

Oh, well you're correct there, the comma should be outside

Sorry for the double post, but I've got to say this: thanks for catching the errors, ralphdspam, I like it for two reasons:

1. Readers will not have so many errors
2. It shows that you are understanding asm from reading these tutorials, which is what I was aiming for

Quote from: Lesson 11 Page 3
B_CALL _VPutSN
Displays a string specified by HL. The string does not end in a
zero. Instead, the number of characters to display is stored in
register B.
Examples: LD HL, String
LD B, 11
B_CALL PutS
String:
.db “Hello World”

Is that supposed to be B_CALL _VPutSN?
I am kind of confused.

EDIT: I could not find this command in the new tutorials.

No need to be confused.  That is indeed another typo

Also, I think:
Quote from: Lesson 11 Page 13
B_CALL _ClrLCDFull
ld d, MainMenuItem1X ; Stores the X position for the menu
ld e, MainMenuItem1Y ; Stores the starting Y position for the menu
should be:
Code: [Select]
     B_CALL _ClrLCDFull     ld d, MainMenuItem1X ; Stores the X position for the menu     ld e, MainMenuItem1Y ; Stores the starting Y position for the menu
EDIT: This is not in the new tutorials.
