Let’s work on the routine to display the menu. I’ll give you the
code line by line, and explain it on the way. Create a new text file called
“ASMGorillasStartProgram.asm”, and include this in
“ASMGorillasMain.asm.”

Finally, go to “ASMGorillasMenus.asm” and replace the top four
lines with the following line:

I think the file created in lesson 11 was supposed to be named "ASMGorillasMenus.asm". 

EDIT:

Wait, it's no wonder you're finding all these typos.  You're looking at the old lessons, and I know that because I canceled ASM Gorillas.

  
Oh, I didn't see that. 
Can you edit your first post on your lesson thread?  I hope no one else makes the same mistake.

BTW, which lesson should I start on now? (I was on lesson 13 before.)

Ok.  Thank you, Hot_Dog for directing me to the correct tutorials.  
I edited all of my old posts with the correct lessons.  

The last three errors are no longer in your lessons because you do not have those lessons anymore.

I just want to thank you because your tutorials are really teaching me ASM.  

I understood lesson 5.  I guess that is a neutral opinion.  

.option BM_SHD = 2
.option bm_min_w = 8
#include “ti83plus.inc”
.org $9D93
.db t2ByteTok, tAsmCmp

should be:
.option BM_SHD = 2
.option bm_min_w = 96
#include “ti83plus.inc”
.org $9D93
.db t2ByteTok, tAsmCmp
Also:

LD HL, Divide_By_4_23
LD DE, OP2 ;Division requires two numbers, so OP2 holds our second one.
LD BC, 9
LDIRB_CALL _FPDiv ;Multiply 1.5 by 3
ld hl, 0 ;Where we want to display the result on the screen
ld (penCol), hl
ld a, 11 ;Displays 10 digits
B_CALL _DispOP1A
B_CALL _getKey

Thanks to lesson 11, I can do this :

I'M glad to see more people can learn ASM with these tutorials. However, I lost again.
