Well, you can stop trying to use a string as a hash reference?
For starters, you should never name variables $a or $b because these are
special variables if you ever do a sort.
Besides that, though, you are assigning $a the value '20020603'. Then you
assign the value of $a to the hash key $a, making that key a string as well.
Then you are trying to access the hash created by dereferencing $h{$a}, only
$h{$a} is a string with the value '20020603', not a hash reference.
So I guess I don't see what it is you're trying to accomplish.

Subject: Can't use string as hash ref?
How do I do the following without getting the message
Can't use string as hash ref while strict refs in use
use warnings;
#use strict;
my($a, @b, $c);
$a = '20020603';
$b[1] = 'name1';
$b[2] = 'name2';
$b[3] = 'name3';
my %h;
$h{$a} = $a;
$h{$a}->{$b[1]}= 1;
$h{$a}->{$b[2]}= 2;
$h{$a}->{$b[3]}= 3;
print $h{$a}->{$b[1]} . "\n";
print $h{$a}->{$b[2]} . "\n";
print $h{$a}->{$b[3]} . "\n";
