Thanks for this bug fix. You too Matt. There is a similar set of minor bugs
in many other structures too, in that they use Long instead of UInt and thus
return a signed 31-bit value instead of an unsigned 32-bit value.

I've fixed the fetch() and store() routines to treat UInt and Long correctly
too.
