It depends on the value of $job_type, I guess. It works fine for me (see below)

Addendum: Are you sure the value of $job_type is what you think it is? 

#!perl
use strict;
use warnings;

print "Content-Type: text/html\n\n";
print "<html><body>\n";

my @jobtypes = (32, 64, 64|128, 128|256, 64|256);
for my $j (@jobtypes) {
    setBu($j);
}

print "</body></html>";

sub setBu {
    my $job_type = shift;
    my %bj = (64,'D', 128,'A', 256,'H');

    print "<ul><li>Job type is $job_type:<ul>\n";
    foreach my $flag (keys %bj) {
        my $bu = $bj{$flag} if ($flag & $job_type);

        # <solegaonkar> But, somehow, I find that the bitwise & return
+s
        # true for all the values! Hence the end result is not good. 

        # -- Does it?
        if ($bu) {
            print "    <li>Bu is true for flag $flag</li>\n";
        } else {
            print "    <li>Bu is false for flag $flag</li>\n";
        }
    }
    print "</ul></li></ul>\n\n";
}
