ITYM values and not "Values" and values returns a LIST and not an ARRAY. What is the difference between a list and an array?	[reply]

Well, it returns two arrays. How do I get the program to spit out `[1, 2, 3, 4]; [9, 8, 7, 6]` ?	[reply] [d/l]

Thanks stefby, that works. But I don't understand why. Where does `$_` derive from in this case, and why do I need `""`?	[reply] [d/l] [select]
