--Synopsis: --
-- --
--Note that the Process procedure does not return to point of call. Instead --
--it raises an exception which is trapped by the main program, which causes --
--the program to stop politely. --
-- --
--The use of the State variable makes it easy to see where fatal errors may --
--occur --
