This procedure produces a new label in sequence each time it's called. The labels consist of all possible combinations of the characters given in the argument the first time it is called. See star(s) in gener.icn for a generator that does the same thing (and much more concisely). ____________________________________________________________ Increment a counter and convert to a label.
