When creating a large program, you may find it helpful to break it up into several smaller source files. (If you are creating a very large program, breaking it up may be necessary, since the entire source code won’t fit in RAM all at once.) You may also find it useful to place commonly-used subroutines in separate files, so that they can be used by multiple programs.

Each program source file contains a list of other source files that it uses as libraries. When you compile your program, all of its libraries, and all of its libraries’ libraries, and so forth, will also be compiled into the output file. (If a particular file is listed more than once, only one copy of it will be included in the final program.)

To edit the list of libraries, go to the program section editor, press [GRAPH] (“Menu”), and select “1: Libraries”. Initially the list will be empty. Press [Y=] (“Add”) to add a file to the list; press [WINDOW] (“Del”) to remove the selected file from the list.

I found the shortcut keys VERY useful.

I've made a "hello World" program that outputs the amount of free RAM on the screen.

I've made a simple DispHL program.
(You see, my calculator is missing at the moment and I'm not done with the program...)

At Ben, how hard would it be to recreate it using no bcalls or TI OS dependant code? It could be ported to KOS so we can work on stuff for it while at school!

I made a program that outputs a 4KB table of DAA outputs (the AF register), given all different inputs of A and the N,H,C flags. This table should be useful for when I start my Nspire Z80 emulator again.

Hahahahahaha

Only if there's 64MB of ram on the z80 that I don't know about
