ON NEXT RECORD
	if current_record_num$() = current_record_count$() then
	begin
		reject operation
	end

ON PREVIOUS RECORD
	if current_record_num$() = 1 then
	begin
		reject operation
	end

Note that with a little thought and a couple of flags and the use of the
"BEFORE FIELD" section for the first field in the record/form, you can
make your multi-occurrence forms circular (like ACCELL menus).  That is,
you can make NEXT RECORD on the last record go to the first record and vice
versa.
