Equivalent to {PROP:LibHook,22}. Assign the ADDRESS of the overriding procedure, and the runtime library will call the overriding procedure instead of the default CLOSE procedure. Assign zero and the runtime library will once again call its internal procedure. The overriding procedure's prototype must be exactly the same as the CLOSE procedure found in the BUILTINS.CLW.
