status.i4.v = acnet_callback_handle(net_handle.i1a.r [,node_name.i1a.r])

	This routine initializes the network handle used by the ACNET
	request callback facility.  This function is called once at
	initialization by intype for console applications.  "net_handle"
	is the ACNET network name to which users should send requests.
	intype computes the UTI network handle for console applications
	by adding one to the first character of the main ACNET task name.
	For example, PB1234 will become QB1234.  The Open Access Client
	(OAC) shell calls this function with the main ACNET task name with
	the first character set to "Z".  Other processes should use the
	same algorithm as the OAC shell.  If this function is not called
	before the first call to acnet_callback_init, the default ACNET
	handle will be used.

	net_handle	ASCII network handle (PROCESS_NAME_LEN characters)
	[node_name]	virtual node name
			(default is NULL which results in using the
			 default ACNET node for the caller's computer)

	This function returns ACNET status values as follows:

	OK			success
	CLIB_DUPREQ		network handle already established

	This function requires the following include files:

	cnsparam_h, acnet_h, acnet_errors_h

	Related functions:

	acnet_callback_init, acnet_callback_flush, intype, window_intype,
	acnet_callback_handle_return, nonconsole_program_init

	C/C++ usage:

	static const char	net_handle[] = "QA1234";
	char	*node_name = (char *) NULL;
	int	status;

	status = acnet_callback_handle(net_handle,node_name);
