MAX FILES OPEN

[TNG TaiHou <ISSTTH@NUSVM.BITNET>]

Hello from Singapore.
My colleague (sp?) works extensively on MCL and recently encountered
a Maximum Files Open error. Well I have heard about the number of files
that can remain open at any one time, I have not really messed with it.
Can anyone point me to a solution to increase the number of files
that can be opened at any time and also explain why this limit
is necessary and how I can generally avoid or increase it, not just
on MCL but any program?
Please email to isstth@nusvm and I will summarize. Thanks.
