Steve,

This was great, thank you!

I am having a problem with the convert.zip program that I'm not
experiencing with the online version of the code.

I'm getting different results converting from bsw2008 to bsw2010
depending on whether I use the website or convert.zip: 

www: 00800110f8a7f8b382c0f8b9f8c1
zip: 00800110f8a7f8b386e0f8b9f8c1
                      ^^       

When I use the bsw2010 code to calculate a bswrev3, I get different
results too:

www: 0fb10038d39240c41826538c39241e426
zip: 0FB10038d39238f39b27038c3923a13a9
      ^^     ^^^^^^^^^      ^^^^^^

Testing has show that the www version is correct.  I get strange
results with my local copy of convert.zip.

For reference, here is the program I'm using:

#!/usr/bin/env php
<?php

include 'swis.php';
array_shift($argv);
forEach($argv as $bsw2008) {
  $bsw2010 = bsw2bsw($bsw2008);
  $bswrev3 = bsw2bsw3($bsw2010);
  printf("2008: %s\n", $bsw2008);
  printf("2010: %s\n", $bsw2010);
  printf("rev3: %s\n", $bswrev3);
}
?>


Is convert.zip out of date?  Am I using it incorrectly?  I surmise
the online version does differ from convert.zip, because the
hexadecimal strings in bsw2bsw3 are capitalized in convert.zip
and the web version emits lower-case hexidecimal numbers (I of
course understand this is an immaterial difference.)

Help?

-Alan
