in thread Need a better way to break out a range of addresses...
It wasn't so easy to see the solution at first. I shut the computer off and went for an easy chair to try and figure it out. I could see that I wanted all combinations of the values that expressed a range but I didn't know how to generate them. Then, it occurred to me that the values that were just one number were also a set - a set of one. So then, the solution came to me!
CPAN - what a treasure!
