I doubt it... The OS architecture has remained essentially the same throughout its versions.
The only possibly new bcalls (which may not be in any standard include file, not to mention the 84+ series is over a year old anyway) are 84+(SE) specific ones, which wouldn't be covered by Hot_Dog's tutorial for a long time.

In lesson 9, on page 12, I had the following text in bold:

Whenever you see a function that has a parameter
of a one-byte value, you can also use (HL) inside that parameter.

That was a mistake.  Instead of "one-byte value", it should be "one-byte register."

I think you should say somewhere that IX and HL are always mutually exclusive. There is no instruction that can take HL and IX as its arguments.  (so you can't do add hl,ix)

Certainly, although so far, I haven't told the reader what IX is  Cool

Well, actually, the major exception (which I didn't realize for quite a while) was that the "ld h,(ix+n)", "ld l,(ix+n)", "ld (ix+n),h" and "ld (ix+n),l" instructions are actually quite valid.

By the way, I haven't got time to check the tutorials yet, but are you planning to have a section specifically for stuff that is not compatible with the TI-Nspire, discouraging their usage unless absolutely needed (for speed, for example)?

Actually I don't think he's going to describe undocumented instructions (unless they are in an appendix). Smiley

Aaah ok. Well, if he ever do any doc on them, he should probably warn that those will not work on the Nspire.

I think I'll put them in an appendix.  Thanks, btw, I'll be sure to warn about Nspire compatability.

Also, .org 40339 should be changed to .org $9D93, because RAM addresses are generally expressed in hexadecimal.

Don't worry about it Ralphdspam.  The topic wasn't up at that time.
