When you find properties in the TIBO components that don't have anything
except the (re)declaration, you should click the Hierarchy button and look
for it in the TIB_ wrapper classes.

For a scrollable dataset, if true, it causes all rows to be fed through by
the server without further control by the client. If false, IBO will fetch
"windows" of rows into the buffer as and when required. For a lookup
dataset, it's generally better to have it set True.
