Thanks for the suggestion (by you and others) for using a loop exit. SPARK has
some restrictions on how 'exit' can be used; I'm not sure if they will apply
to my case or not, but I can look into it. In my case there is also a state
machine involved and the exiting would have to take place inside a case
statement inside the loop. I seem to recall that SPARK has an issue with
exiting from nested control structures but I can experiment.
