Not a tutorial, but the only one meaningful source about ASIS I know is
http://www.sigada.org/wg/asiswg/
It contains documentations and some examples, some rather complete.
For examples, look at
http://www.sigada.org/wg/asiswg/ASISWG_Results.html
You may want to search for the two links named =E2=80=9CPublically avail=
able ASIS  =

Applications=E2=80=9D and =E2=80=9CHow to do things in ASIS=E2=80=9D in =
the latter page. Good  =

point to start, beside the specification files of your compiler's ASIS  =

library.

-- =

There is even better than a pragma Assert: a SPARK --# check.
--# check C and WhoKnowWhat and YouKnowWho;
--# assert Ada;
--  i.e. forget about previous premises which leads to conclusion
--  and start with new conclusion as premise.
