list_field_read_c

	status.i4.v = list_field_read_c(identifier.g.v, entry_text.i1a.r,
					entry_index.i4.r)

	This routine returns the current entry for a list field created
	by an earlier call to list_field_create_c.  If either of the
	returned parameters are not needed, a value of NULL can be passed
	for that argument.

	identifier	identifier of desired field whose type depends on
			the most recent call to list_field_set_id_type_c
			(LIST_FIELD_BY_ID -> use four byte ID value returned
					     by a prior call to
					     list_field_create_c (default),
			 LIST_FIELD_BY_HANDLE -> use ASCII handle string)
	entry_text	returned current entry text
	entry_index	returned current entry index

	This function returns ACNET status values as follows:

	OK			success
	CBS_NO_SUCH		list field does not exist

	This function requires the following include files:
