OCI Parameters
Chapter 38
38-7
Function
Before changing this parameter make sure you have read and understand
the watchlist concepts outlined on page 38-5.
Use this parameter to specify the size (in bytes) of the foreground
watchlists for all connected OCI stations. Each OCI station that connects
to the 9/Series creates its own background and foreground watchlists. All
foreground watchlists created are the same size as specified with this
parameter. The foreground watchlist is typically very small as most
applications do not use foreground watchlist items. Refer to your 9/Series
OCI API developers guide for a listing of the data items that are
foreground and their data types.

as a background watchlist (see page 38-6)
