Absolutely what I was looking for yours and the one above -- I don't know what I was doing wrong when I tried it ...oh, I remember, I was trying to use map directly with the hash -- thinking it would treat it as an array and I could get through the keys/values that way..., but map only works on array according to the manpage.

So then I started looking at the hash specific functions...

Too bad 'each' doesn't do what keys/values does -- I tried 

@array=each %hash;, 

#and

@array= [each %hash];...

but never got it to do what I wanted...sigh.

I've used map with values before, but was thinking there should be some way to do similar with 'each'...but each is just demented...1 item at a time...w/no slurp-ability......

And there I am with a straw trying to make it work...
