That was one of the tries I'd made but not included in my initial post.  

---------------------

print "HewTrace004 - from 1st for block at top of PP pg 277 \n";
my @hewArray;                                      
for $hewArray (keys %hashStats)                    
 {                                                 
   print "$hewArray @{ $hashStats{$hewArray}} \n"; 
 }                                                 

Global symbol "$hewArray" requires explicit package name at hewtest.pl line
24. 
Execution of hewtest.pl aborted due to compilation errors. 
(Line 24 is the print statement.

Changed to:

for my $hewArray (keys %hashStats)                 
 {                                                 
   print "$hewArray: @{ $hashStats{$hewArray}} \n"; 
 }                                                 

and got
Can't use string ("ARRAY(0x4a68d4)") as an ARRAY ref while "strict refs" in
use
at hewtest.pl line 25.
