[Coco] ASM

[L. Curtis Boyle]

In order to make an exectuable module, you have to define some things in your ASM source code (otherwise, it just kind of acts like a code validator).

If you are using any OS9 DEF’s (like system calls, etc), you will need to include:
	ifp1
	use /dd/defs/defsile
	endc

(whatever defs files you need) next.

	You will also need the ‘mod’ (before your actual data area and program code starts) to set up the module header. Since, in another email, you mention that you are using the def files already, you should have some of these define, so you can do something like:
tylg	set	Prgrm+Objct
atrv	set	ReEnt+rev
rev	equ  1

	mod	eom,name,tylg,atrv,start,size

then your data area (this is just some sample code; obviously yours will be different):

Var1	rmb  1
Var2	rmb	2
…
size	equ	.		(This defines your data area size)

Then, define your program name (which is used in the MOD command above to make the module name)
name	fcs	/MyProgramName/

Using the above MOD statement, you also need to define ‘start’ (start address of your program), and ‘eom’ (end of your program).
start is just a label to put at your first program statement you start running at, and eom you can set up at the end of your code:
	emod
eom	equ	*
	end

That should let you compile to a file.
