status.i4.v = dio_set_redirection_slot(slot.i4.v)

	This function provides for establishing a slot ID in a central
	node for the purposes of data acquisition redirection.  All
	redirection is designed upon console number and slot.  By default,
	central processes have a slot id of -1 (no slot).  The include
	file dpm.h defines reserved slot assignments for central processes.
	Users of this routine have the responsibility to clear redirection
	for their process with the companion routine
	dio_clear_redirection_slot.  These routines will not work on
	console nodes.

	slot		central slot to redirect

	This function returns ACNET status values as follows:

	OK			success
	CBS_NOTENB		not valid on this node
	CBS_INVSLOT		invalid slot value passed
	DPM_OUTOMEM		DPM has run out of shared memory
				(some requests on this node must be canceled)

	This function requires the following include files:

	clib_h, acnet_errors_h

	Related functions:

	dio_clear_redirection_slot, dio_redirect

	C/C++ usage:

	int	status;
	int	slot = SRSAVE_WHACK_SLOT;

	status = dio_set_redirection_slot(slot);
