Well, if you actually want to know what the format is, then check out these two awesome sections I wrote on wikTi. Certificate/Headers and Certificate/Header fields where you will be most interested in the the $8XX fields.

However, if you are normal, you can just make it with TI's AppHeader Utility that was found on this page.

Sure, here you go, just change the name to whatever the name of your app is, and make sure you don't change the total number of bytes. So pad with either 00 or spaces so that the name is 8 bytes long.

If your app is more than one page long, change the bolded byte.

No, that goes right at the very start. Your header will look like this:

.nolist
#include "ti83plus.inc"
.list
.org $4000

;app header
;
;
;
;
;header end

bcall(_clrLCDFull)
;etc...

Edit:
    That doesn't have to be bcall(_clrLCDFull)

Edit: Why is it 3 digits in the .db's? Does it need to be that way in data too, or just for the header?

I'm going to guess that that's how TI originally wrote it, even though it doesn't make sense.

If you're using the h suffix to define hexadecimal values, the first character must be a digit. Thus you have to put a 0 behind all values $A0 to $FF, and you might as well do it with $00-$9F too, for consistency.

So why isn't it written with '$' ?

Alright.
Interesting.  Thanks for the info.
