This example assumes that the 'tver' resource will always have a
resource id of 1. If this is only used with your own code, then you
can enforce this constraint, but if you're getting the version number
for any PRC, then you have to also check for a 'tver' with resource
id = 1000.

This is a good point...falling back to the version number in the DB
header if you can't find a 'tver' resource is the right thing to do.
Though _every_ PRC should have a 'tver' resource, if it's
well-written Palm OS software.

You can't.
