status.i4.v = input_field_read_c(identifier.g.v, current_value.g.v,

	This routine returns 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)
	current_value	returned current value
	array_index	array index of value to read (starts at 0)

	This function returns ACNET status values as follows:

	OK			success
	CBS_NO_SUCH		input field does not exist

	This function requires the following include files:

	cbslib_h, acnet_errors_h
