i see it doesn't matter wheter you write If...Then...End, or just only If, it just starts a new highlight block, while the End command will be never found while looping through the code. so there is an error in the syntax highlighting: when there is a single If in BASIC (not in Axe), just only the next expression* should be highlighted is that color, not all the other code in the file.

Then there is a question you will now the answer to (I think): which type of checksum is used in the program header?

*this is not necessarily the next line, because there can just be a semicolon between the If statement and the next expression

well, I don't really know how to explain. when you want to write a 8xp file that could also be send using TIconnect, it should have a valid checksum or so stored in the first few bytes of the file. when that is not done correctly, TIconnect wouldn't send it to the calc, and perhaps even other linking programs won't do it. I would like to know how to create that checksum, so I can write valid 8xp files, so I don't have to export all my data created by my progs in plain text, and then use cemetech or your prog.

which class is for writing the file?

EDIT: I found it!
am I allowed to use your code?

Hmm, ok it seems that that "o" is one the couple BBxx tokens I didn't add... sorry I misspoke. the "a" is definitely added there as an "a" tho, I don't know why it would be showing "n" (the letters in quotes are the special symbols im to lazy to find to copypasta )
@LordConiupiter Sure, but that code might not really work too well (be easy to work with), If you want, I could wrap it  into an easy function that you can just copy in if you want...

Well, since it's unsure whether it's one or two bytes, it just tells you both then skips one. AKA "CB" = "cosh-1", since it just skipped the CB (I mean BB ) part...

Well I found a bug. When a program is being opened that has the expr( it displays it as "Exch(" as individual tokens.

Also, I don't think this is a bug in the program but for what ever reason this won't just start up from the executable. I have to run it from the executable inside the .zip file Just thought I'd mention that since it involves it.

What do you mean about the Axe thing? expr( isn't an Axe token, nor was this an Axe program. I'm confused.

As for what I mean. I mean when the program with expr( opened up at each place where expr( was it showed "Exch(." Then when I moved it back to a calculator, I did it before I noticed the bug, it was like someone just used [ALPHA] to type each letter and parenthesis in. Make more sense?

Oh ok, my bad. I didn't know Exch( was a Axe token. But even if it is a Axe token shouldn't it have saved it as if it were expr(, or something like that?

As far as I know it's just doing it with that. I haven't tested anything else.
