While it might work, its not really needed.
Why can you not put that code in Activity_Create?

the result of that code is a variable that needs to be accessible also from a service module.
The service module is started at boot and I want it see that variable, without creating the main activity and without waiting the main activity is started from the user.

So, the choices in my mind were:

1) duplicate that code both in the service module and in activity_create
2) put that code in Process_Globals

But I'm not sure what I'm thinking and saying is correct.

I think duplicating the code will be a better/flexible option.
(You do not need to duplicate the code, just put it in a code module, and call it from both places).
The problem is that at boot, usually the sdcard is not ready, so your app will crash if your try to access the filesystem in process globals.

If you do duplicate the code in both places, make sure you do not re-initialize the variables (if that is relevant) by using IsPaused(Main) or IsPaused(Service).

Thank you. This would make thing easyer for this and other parts of my program. But I was reading in this post

http://www.b4x.com/forum/basic4android-getting-started-tutorials/7542-service-modules.html#post42973

that "Note that it is not possible to use CallSub to access subs of a Code module."

and I discarded that way. So, is it possible instead ?

Yes, you do not need CallSub with code modules.
If you have a sub called ReadMyFile in a code module called FileUtils, you call it like:

B4X:

FileUtils.ReadMyFile

You can access process global variables in code modules as well.

Careful with reading files upon a device boot, as already said by thedesolatesoul.
I have similar code in a service which starts at boot, what I do is to check for the files (until the sdcard is ready) by creating a timer. I process everything else, only when finally my sdcard is readable.
