] The call you need is DOS Fn 67H.  The specs for it are:
] 	AH	=	67H
] 	BX	=	the desired number of handles (up to 0FFFFh)
] 
] Once this takes effect, it remains in effect for ALL processes in

] statement in CONFIG.SYS - which makes it sort of redundant. :-)

1) this has effect only for the process which calls it.
2) the FILES= limit still applies.
3) i know both from personal experience.
