The Cursor Library can provide support for scrolling cursors when the underlying driver doesn't, and can also allow "simulated" positioned updates. With USECURLIB=YES, the Cursor Library will always be used. With USERCURLIB=NO, it will never be used. With the default USERCURLIB=IFNEEDED, it will be used if the application tries to do something the driver manager thinks the driver doesn't support. To use a scrolling cursor with the Cursor Library, you must use a STATIC cursor. To do positioned updates using the Cursor Library, you must use OPTCCVAL concurrency.
