работа с базой записей, поиск удаление Опции

[and 1]

Посмотрите пожалуйста, что не так. (иногда может выбить ошибку 200, но это неважно). В меню записываются фамилии, успешно добавляется, но когда выбираешь показать все записи (не сортировать, по фамилии...) экран пуст. Может что-то неправильно в процедуре Writephone. Или они попросту не сохраняются?

вот исправлено по 12 посту, но выбивает опять ошибку такую что не удается найти файл. Что я совсем запутался в теме Файлы

Assign (PhoneF, filename);
Reset(PhoneF);
