%parsed has a inventory number in the key, and and 8 fields list in the value. 
The 8 fields are all simple text: title, author, date 1st published and so on.
Here is a simplified version of what I am shooting for.  It also doesn't "work
right."

#!perl 

@list_1 = qw (pig dog cat horse elephant tapir); 
@list_2 = qw (north east south west up down);
@list_3 = qw (apple orange papaya goyaba plum);

$parsed{1} =[ @list_1];
$parsed{2} =[ @list_2 ]; 
$parsed{3} =[ @list_3];
    
%saveparsed =%parsed;

foreach $num (keys %saveparsed) {
    print STDOUT "\nSAVEPARSED $num:  @{ $saveparsed{$num} }  ";}

dbmopen(%saveparsed, 'parsed.nsh', 0666) || die ("Could not open parsed: $!");
 %saveparsed =%parsed;
foreach $num (keys %saveparsed) {
    print STDOUT "\nSAVEPARSED_x $num: @{ $saveparsed{$num}}  ";}
dbmclose(%saveparsed) ||die "Couldn't dbmclose: $!"


############OUTPUT##################
SAVEPARSED 1:  pig dog cat horse elephant tapir
SAVEPARSED 2:  north east south west up down  
SAVEPARSED 3:  apple orange papaya goyaba plum  
SAVEPARSED_x 2:   
SAVEPARSED_x 1:   
SAVEPARSED_x 3:   

######
I had expected it would give the same output in both print loops (with the
exception of the "_x" of course.)
