How about this:
##################################
my %hash = (alpha => 'one', beta => 'two', gamma => 'zero', zeta =>
'cheese');
print "Sorted:\n";
foreach(sort {$hash{$a} cmp $hash{$b}} keys %hash){
print " $_ => $hash{$_}\n";
}
print "\n";
print "Unsorted:\n";
foreach(keys %hash){
print " $_ => $hash{$_}\n";
}
##################################
Also, if you want to do a numeric comparison, then you should change the
'cmp' to '<=>'.

Hey Timothy,
I couldn't get it to work.......I know you can sort on keys, so I went out
the cheap way....I switched the values with my keys...it's no problem
because my values are unique also....
If anyone is interested... as sort on keys...........
foreach $key (sort keys %hash)
{
$value=$hash($key);
#do something......
}
