Beginner question: How to use an Include file for own functions (sub routines)

[thyslo]

Suppose I have an assembler program that consists of the file main.asm and works. In this program there is a call

	bsr test_func

In test_func some things are done and then it ends with rts:

test_func
	moveq #111,d0         ; Imagine something useful here
	rts

I now refactor the code and move test_func to its own file my_functions.asm. And in main.asm I add the follwing line at the beginning:

	include my_functions.asm

The problem now is, by doing so my_functions.asm becomes the program entry and terminates the program right from start with rts.

I come from C, and there includes are included at the beginning of the file and the functions are called further down.

How is this properly done in assembler; are the own helper files included below the main code to avoid the entry point problem?

Don't include at the beggining, or add "bra your_main_function" before the include statement (that bra will become the first instruction of your program).
