Hm. I doubt that. This would actually set the variable to
True or False.

Solutions: REQUEST.get() can take a default value:

foo=REQUEST.get('foo',0)

which will return the actual value or 0

Also, ZSQL Methods DTML have default value
modifiers - check Zope-Book for details.

Of course it depends on what Laura is really doing here.
