so... unless it says .org 40339 or .org $9D93, you continue on where you left off?

Exactly.  The .org 40339 or .org $9D93 means "begin a new program."  Otherwise, continue the program from the last page.  So the red boxes from pages 6 to 8 are one big program.

Start off by changine Big_Size .equ 2 to Large_Size .equ 2.  That was a typo.

Then put parenthesis at the end of ld a, (Player2+1

Finally, look at the code box in your post and remove the lines I put between rows of dashes, such as ---------------------------------------------------

Well, it's actually not something you're supposed to run, so it doesn't matter.  I forgot to say that it's just hypothetical.

Try not to double post in the future

As a rule of thumb, if you see a space, you can do as many as 1 space or as many as 20 spaces.  The number of spaces doesn't matter.

However, if there's no space, don't put in a space.

Here's two examples:

No space before Load_Player3_Data

For call Load_Player_Data, you could type in  call                Load_Player_data

I have a question about page 10 from lesson 7.

If you check that A <= 90 shouldn't the ASM equivalent be CP 91 instead of CP 89?
Since you check for the C flag condition, if A were 90 or 89 it wouldn't be set.

This program gives you a graphical representation of the "fnint(" function, which allows you to calculate definite integrals. It is extremely similar to the functionality MathPrint provides, minus the extreme bloat that slows your calculator down to a crawl.

Assuming coolsnake's account of the tutorials are accurate, then it should indeed be "cp 91", like he said.
