re out a way to port that source, but if a cookbook existed, similar to the=
 doc for an RTOS that tells what each stub subprogram must be coded to prov=

art appearing on a lot more varied hardware, and start getting noticed by a=

I agree.

So, you start with system.ads, You start by defining it's number types, sto=
rage types and memory types. Look at the private section of the file, it ha=
s some parameters you set telling you that the docs are in targparm.ads - w=
hich they are. If you don't need anything else, that's it. If you need more=
 runtime, you have to look further into the source.

If you need to return unconstrained types, like String, then you can create=
 your own secondary stack package, look at s-secsta.ad[sb] and use that or =
modify it or create your own. You will need to look at the binder at this p=
oint as the binder can change the size of the secondary stack.
