status.i4.v = input_field_set_c(identifier.g.v, new_value.g.v,
					array_index.i4.v, exec_callback.i4.v)

	This routine sets the current value for an input field created
	by an earlier call to input_field_create_c.

	identifier	identifier of desired field whose type depends on
			the most recent call to input_field_set_id_type_c
			(INPUT_FIELD_BY_ID -> use four byte ID value returned
					      by a prior call to
					      input_field_create_c (default),
			 INPUT_FIELD_BY_HANDLE -> use ASCII handle string)
	new_value	new value
	array_index	array index of value to set (starts at 0)
	exec_callback	execute callback function flag
			(TRUE -> execute callback function,
			 FALSE -> do not execute callback function)

	This function returns ACNET status values as follows:

	OK			success
	CBS_NO_SUCH		input field does not exist
	CBS_INVARG		invalid value passed
	CBS_RANGE		passed value is out of range

	This function requires the following include files:

	cbslib_h, acnet_errors_h
