As long as your profile looks for the values specifically this is
not really a problem.

In other words from a possible selection of CHECKBOXes A-Z,
if you already have checked A,B,C,M,Q and you get back
B,C,Q,S then that is fine and long as the profile knows how to
rebuild the value.  We typically keep it as an array or
delimited string, not as separate values; that probably makes
it easier.

There is another brute force way.  You can set a second 
HIDDEN VALUE=0 to unset the CHECKBOX.  If the first one is not
checked (and therefore not sent) your hidden value will be found.
If it is checked, then the CHECKED value will be found.  You want
to =~s/\000.*//; the value.  This way gets into problems
with if($value) because it will exist when you might not expect
it.
