Close, but not quite; there's another entity around involved in creating file handles...our friend, the dos.library. Those fields are used for the BCPL buffered IO calls. Which, under 2.0, are now available for use by non-BCPL programs as well. Anyway, those fields are private to dos.library and the shell...and under 2.0 finally can give any program that needs it buffered IO easily. andy -- andy finkel {uunet|rutgers|amiga}!cbmvax!andy Commodore-Amiga, Inc.
