Dear Monks--

Solved it! Wasn't a hash/array problem at all -- though I'm still not sure why I couldn't print out a list of keys. Anyway, it's working now...

Thank you for all your comments: I know there are better ways of doing things; I'm trying to set the basic thing up first, & then I'll clean it up. What I don't understand is how my code is different from Larry Wall's in PROGRAMMING PERL. Here is his code: 
for $group ( "simpsons", "jetsons", "flintstones" ) {
    @members = get_family($group);
    $HoA{$group} = [ @members ];
}

Do I need to dereference something here to get at it ?

For those who are wondering, @array2 has this kind of data: 
"0451524934","1984",7.9500,67,"Penguin Putnam"
"0618056815","42nd Parallel",13.0000,25,"Houghton Mifflin"
"0195167929","A Strange Likeness - Becoming Red and White in Eighteent
+h Century",29.9500,0,"Oxford University Press"
"0520204026","Abortionist : A Woman Against the Law",25.0000,30,"Unive
+rsity of California Press"

Later in my program I push stuff from @array1 onto each array in %Tex. At least in theory. It's weird how many examples, particularly of MySQL, use book information as examples, because that's what I am -- a bookseller.

jdporter added code tags around the data
