Code was added to support listing of so many values, the default is 0 (zero).
<br>The generators lie dormant until a request is made (illustrated by the calling of "TELL" to display some values).
<br>A lot of unnecessary iterator calls could be eliminated (and making the program a lot faster) if a check would be made to determine if a value has been emitted.
<br>The REXX program can handle any numbers, not just positive integers; one only need to increase the size of the DIGITS if more are needed.
