I say "script" for tiny things and "program" for more serious things. Some people spend lots of energy arguing this topic. I don't recommend you spend any energy caring about it.  :)

Theodore++    I'm still doing what that does manually. I have no good reason to do so.  :)

Code looks good to me if you want to make 26 LDAP queries. If 1 LDAP query would be better for some reason you could pull everything into memory and write each letter to disk later.

Note a..z isn't gonna work worth a damn if you have any Japanese employees. My good friend 愛子 will feel very left out of your directory.    :)

I believe the preferred modern form of this is:

   my $filename = "/www/wjgilmore/directory/$letter.html";
   open my $fh, '>', $filename or die "Can't write to '$filename'";
   say $fh $toc, $directory;
   close $fh;

Hope that helps,
