tasks, protected types and entries

Hi,

What is the difference between an entry and a procedure?  I think the
difference is that a procedure will always execute regardless of any
condition, but that an entry can have a guard to allow/prevent its execution
if a given condition is satisfied.

So for a (protected) queue, the procedure Enqueue (someitem) would run in
any circumstance and the entry Dequeue (an_item: out sometype) would run
only when it is sensible to do so.  i.e. when there are items in the Queue.

Is that correct?  Is it the same for tasks?


Happy St Paddy's Day,
