Z80 Assembly in Linux?

[Yes]

I'd like to do some Z80 assembly programming for my TI-83+. I tried using the Z80asm program in Synaptic but it always says there's something wrong with my code. I think I remember doing something before compiling the code with TASM in Windows, so I think that might be the problem. So, how do you all write Z80 programs in Linux?

Here's the code, if you think it might be a problem there:

#define B_CALL(xxxx) rst 28h \ .dw xxxx
#define B_JUMP(xxxx) call 50h \ .dw xxxx

_clrlcdfull =4540h
_homeup =4558h

	.org 9D95h
	B_CALL(_homeup)
	B_CALL(_clrlcdfull)
	ret

.end
END

The errors are all

error: command or comment expected (was _homeup =4558h )

It has an error for all the lines of code except for ret and END.

Did you include the ti83-plus include file?

[Yes]

No, how do I do that? Do I need to get the file from anywhere?

Does anyone also have a Linux equivilant for TI-Connect for Linux?

I know it's a bit late, but in case anyone else stops by...

Now there are a bunch of tools and resources for z80 (and 68k) calculator programming on Linux.

For starters, there's the Wabbit suite of tools, particularly spasm (a replacement for TASM):

There's also a Linux IDE (no longer under development):
http://wabbit.codeplex.com/releases/view/45275

And a native Linux emulator (still under development) with lots of features: screenshots, a nice debugger, grayscale emulation, etc.:

You can also run PindurTI through Wine just fine. I haven't had any luck with WabbitEmu, however.

And instead of TI Connect, Linux has TiLP:
http://tilp.sourceforge.net/

For creating tilemaps/sprites, while a bit dated, CalcGS has been the standard for years and works fine under Wine:

And now there's even an online assembler, ORG:
http://clrhome.org/asm/
..which can handle multi-file projects and assemble into a variety of formats (83/+ programs, applications, appvars, etc.) and an online sprite/tilemap editor, Pixelscape (though it only supports 8x8 tiles, i believe):
http://clrhome.org/pix/

That should be more than enough to get you started, things are certainly much easier now than they were ten (or even five) years ago!

EDIT: And to include a file you would write #include "ti83plus.inc" at the top of your program. You can find it here. And while your program will start running at $9D95, assembly programs for the 83+ need to start with the AsmPrgm token. The start of a regular 83+ assembly program usually looks like this:
.org $9D93 ;$9D95-2, because the AsmPrgm token takes up two bytes
.db t2ByteTok, tasmCmp
