I would like to clarify a point in the SDL standard....
If I am in a state in a process and upon receipt of
a signal, call a procedure that itself
has a state included, and then on exit go to the previous
nextstate (dash symbol), what should be the final state?
1. The previous state of the process..
2. The previous state of the procedure..

The standard does not seem clear on this point, unless I
have not found the correct place.
