89 -------------------------
91 -- In this program, we use the phrase "termination" of a file name to

93 -- often this is simply the extension, but in some cases, the sequence
94 -- may be more complex, for example in main.1.ada, the termination in

104 -- element ever enqueued, while Q.Last - 1 is the last element in the Q.
