ntv_handle DEPRECATED

	status.i4.v = ntv_handle(handle.i4.v [,old_handle.i4.r])

	Change the default handle by which ACNET recognizes this
	task. As an option, return the previous default handle.

	handle		longword with the network handle (normally in
			Radix-50 characters) which is to become the default
			for future network calls.  This handle must have
			been previously defined by a call to ntv_connect.

	[old_handle]	longword in which the old default handle is returned.

	status	  VMS completion condition code.

	When a USM or request type message is received and the user's
	AST routine is called, the handle is temporarily changed to
	that of the incoming message for the duration of the AST
	routine. NTV_HANDLE must not be called from any AST routine.
	Similarly, NTV_CONNECT must not be called from any AST routine
	IF it is being called to create a new handle.

	This function returns status values as follows:

	SS__NORMAL	success, default handle changed
	SS__INSFARG	handle argument not provided
	NET__ASTACTIVE	cannot perform function at AST level
	NET__NOSUCHHAN	no such handle found in table
	NET__NOTCNCT	not yet connected to the network

	The following completion codes are indicative of a possible
	internal network error:

	SS__BADPARAM	bad $GETJPI parameter (internal network bug)

	This function requires the following include files:

	acnet_h, ssdef_h
