] 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
] the system. The number of files request can exceed the FILES=
] statement in CONFIG.SYS - which makes it sort of redundant. :-)
]
] Hope this helps,

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