Turning windows hello world eg into a proc in an obj

First, greetings to all.

Second, props to Tomasz Grysztar for fasm - awesome.

Third, help!

I can create a simple obj (MS COFF) for simple things like testing, setting bits, etc. Things that have no includes or macros. Smile

I can also compile the "hello world" example (this makes me an ace, right? Razz

)

However I cannot turn that example into a proc in an obj. In fact I am a bit lost on the whole include & macro thing. (Do I lose my ace status? Sad

)

I wonder if someone would be kind enough to explain how to turn the example:

Code:

include 'win32ax.inc'
.code
  start:
        invoke  MessageBox,HWND_DESKTOP,"Hi! I'm the example program!","Win32 Assembly",MB_OK
        invoke  ExitProcess,0
.end start

into a procedure in a linkable obj file, called, say, alert, with the title, message and flags (flag values or-ed together) passed in as three parameters.

It may give me an "aha" experience.

Thanks!

PS: I have searched and browsed and read the docs, but nothing has rung any bells

Edit: Right after posting this I found something. (Don't you hate that?) I don't understand it yet, but it seems to be along these lines. My apologies for this post.
