For the past few months, I have been learning TI-BASIC programming and have become very proficient in that "language". I have recently been trying to convert the BASIC math programs on my TI-84+ calculator to one flash ROM application. My original plan was to use BasicBuilder 3.0 to compile and compress my programs into a single-page flash app. This has not worked because I receive an error message (Error: [File] has an invalid header) for most of my programs when I try to upload them, especially the larger ones around 6 KB. Apparently, BasicBuilder will compress my programs into a single-page app whereas my programs use 30,179 bytes of RAM memory when on the calculator's RAM (so I would need to make a two-page app). I have all of the algorithms for my math programs written in BASIC but I could not find how to write those same algorithms in Z80. Also, I do have all kinds of utilities downloaded like the whole TI SDK, Rabbitsign/Wappsign, and ZiLOG Developer Studio (ZDS).
Can anyone assist me with the BasicBuilder error or with the development of an app traditionally or with another utility? Any help would be greatly appreciated.

There are a few issues here...
1) To develop an app traditionally, you would need to learn Z80 which is a completely different language, so that's pretty much out of the picture.
2) There isn't 30kb of user accessible RAM on a ti-84 + so I don't know how you are putting them all in your RAM, are you on a ti-84 + CE, in which case BB will not work given the lack of signing key.
3) As you mentioned, BB will only make single page apps and not a 2 page app, so you won't be able to make it work.
3) Why on earth are you making something 30kb, this calls for an optimization job!
If you post your code, I think it might be possible to optimize it down to the size of a single page app (depending on how efficient your coding habits are), and then you will be able to use BB to make it into an app.

I concur with the third point. While I don't know about your specific case, BASIC code can very often be optimized for size—at the minimum, through small tricks (assuming you haven't applied them already), by 10% or so, and often much more. For example, if you have 20 KB of lowercase letters, that can be cut in half by making them uppercase, and maybe translating them to lowercase.

z80 assembly isn't inherently better than BASIC. True, it's several times faster, but math formulas are several times smaller, easier to write, and easier to understand in BASIC.

To clarify, I have a TI-84+ but am not able to put 30 KB of programs onto a calculator that only has 24 KB of accessible RAM. Of my total of 17 programs, 4 of them take up just under 24 KB. If someone could help me with the optimization that would be great. The one skill that I'm not very good at is using loops like "For(" and "While". If someone could help me with the Optimization, that would be great. I apologize if my code is messy, I'm a beginner and the TI Connect CE studio does not allow tabs for indentation. I could take some components out if I need to, I would just like to have it all. I know this is a lot but thank you in advance if anyone is able to help.

I strongly suggest you use xLIB's ExecArcPrgm from its Third-Party Libraries via Doors CS. Just give your main program the necessary header to make it require Doors CS and xLIB, then you'll be able to use that function to copy archived programs into temporary RAM programs, run them, and delete the temporary copy.

In general, using loops instead of Lbl:Goto is better structure, but in this case labels are good because you can use Menu(. The structure is okay.

* Much of your program #4 can be replaced with this list input routine:

Code:

which is like Input L5, except the users doesn't need to enter braces. This has the advantage that the user won't need to retype twenty-three numbers after a mistype on the twenty-fourth.

* Closing quotation marks and parentheses are unnecessary at the end of a line. Some people think it's bad practice to remove them, but you have about a kilobyte of them.
* Disp "" is unnecessary if you won't be using any more Disp commands until the next ClrHome.
* Lbl 42: Goto 32 is unnecessary. Just make the menu go to label 32 instead of 42.
* Make a label like this:

Code:

and just Goto A wherever you display the area, instead of repeating the area-displaying code.

I suggest not using the stop command in the middle of the program. It causes the program to abruptly stop and exit the program unexpectedly. Have a label that goes to the end of the program and it just smoothly ends the program.
