The application calls DBCHINI to initialize the DBCAREA. Before initializing it, DBCHINI first parses the clispb.dat file, if it is being used. An error message is returned if any clispb.dat options are illegal.
After regaining control from DBCHINI, the application’s DBCAREA is initialized with values from clispb.dat, if it is being used, and from the CLI defaults for any values not supplied from clispb.dat.
