QuantlibXL objects question

Hi,

I took the sample QuantlibXL spreadsheet (options.xls)
and plugged a real-time feed into one of the cells. I
see that objects created with
qlGeneralizedBlackScholesProcess and qlVanillaOption
keep changing numbers (...#0000 ...#0001 ...#0002
etc)every time I receive a quote. Does this mean that
every time I update the price of the underlying
QuantlibXL creates a new set of objects? If so, what
is the correct way to use functions in real-time
application.

Also, what is the meaning of "any permanent" in the
documentation? It is the last argument for every
function in QuantlibXL.

Thank you in advance!
Denny
