Yes, it can be used as an extra variable >.> You can store to it, use it for math, and all that good stuff

Also, when I was trying to pass unrecognised tokens to the error handler, I found out that I had broken it. As well, there was another piece of code that has probably been broken for a while that I finally teased out. Anyways, I added these features in all:

• ] can be used to parse an argument where the pointer follows.
• ? is a token that is automatically updated with the program counter whenever there is an error or when you use prgm( as opposed to prgm
• For the error handler only, End) is recognised as a command. This will exit the Error handler without restoring Ans and θ' (this lets you parse unsupported tokens yourself and return values that way).

I am going to see if I can find any more bugs before I release it, though.

EDIT: @Yeong: I saw your review on TICalc, by the way and I've forgotten to mention this:

I just wish that it could support multiple keypresses, though.

You can test directly for keys. For example, getKey(3 lets you test for right and getKey(2 lets you test for left. If you are pressing both keys, a 1 will be returned in both cases.

With the "Full" mode (just like Axe), Grammer programs can be run at amazing 15MHz speed(Of course, the 15MHz limited to 84+SE

Full works on the TI-83+SE, TI-84+, TI-84+SE. Basically, the only calc in the series it won't work on is the TI-83+.

Also, getKey( has been around since the program version

Huh, that is actually weird. I've never had the problem :[ Maybe you added something to your code that caused it?

No, that should work. I will test it at some point, but it has worked for me.

For Yeong's sanity, I will post this update. I have no clue how many bugs or issues were addressed (I lost my progress log), but it seems that the last major release had issues with displaying large numbers and this veriosn has it fixed. As well, there was an issue with the ReadArc routine that was causing crashes. That has been fixed.

Err xeda the fix can't run archived program at all -_-

It gives me ERR:?
Do I have to delete gramVar appvar?

Its a july version.
