To load OS var Pic9, you need to do RecallPic 8 Remember:
0=Pic1, 1=Pic2, 2=Pic3, 3=Pic4,...,Pic0=9

TI names them weird (internally, they start at 0, but to the end user, they display starting at 1).

Btw Yeong I don't think you're allowed to get any help for Illusiat if that's what you're asking above

3) No private help from others. No code help from others. Feedback on screenshots and ideas may be requested (only) in the entry's official Cemetech topic, but keep in mind that we will be grading you on your originality.

Of course reporting Grammer bugs is fine, although you have to be careful to not report plenty of false positive since people might inaverdently help you.

I think I have read somewhere that it might be tolerated if done directly in your Cemetech topic, but you might have to make sure first. Just making sure you don't get in trouble.

Feature request: any other methods other than overwriting with RecallPic.
Also can grammer writr text on backbuffer?

I think we covered a few of these on IRC, but for everybody else:

If Uses everything on the line, regardless of what the token is, even if it is a colon. Colons will separate commands, but does not work exactly like a newline. This allows more complicated math formulas in the conditional.

To draw Text( on another buffer, you will need to make that buffer the main buffer. To set it back to the main buffer afterwards, use Disp pi9340.

Recallpic has the following syntax: RecallPic #[,Method[,Buffer
So to use a different type of logic, change Method:
0=Overwrite
1=AND
2=XOR
3=OR
5=Erase

This has the most up-to-date released readme, I believe.
Grammer 2

I have very little coding space, but I might be able to add that. It is definitely a good idea.

Feature suggestion (in longer terms): TI-84 Plus C Silver Edition compatibility.

Ok cool to hear. From what I gather, unless the new calc is not even a Z80 and lacks Z80 emulation at all, it should just be a matter of address changes like the TI-83 to 83 Plus and different screen, so the non-screen parts of Grammer might not be too hard to port. Of course that might be problematic if you still code everything on-calc and don't buy a new calc, though.
