Многозадачность

Подскажите пожалуйста кто знает в таком вопросе.
Возможно ли параллельный запуск процедур, т.е.

RUN Proc1.p
RUN Proc2.p

Процедура Proc2.p будет запущена только после выполнение Proc1.p. (время выполнения каждой из процедур, например 1 час)

Хочется запустить их параллельно а не последовательно.

Разве что запускать эти процедуры на appserver'ах.

Многозадачность на уровне любой современной операционной системы естественно поддерживается.

Многозадачность на уровне одной программы прогресс (.p) так же как и скажем Оракл (PL/SQL) не поддерживается (в таком виде как спрашивается).
В Оракле есть встроенный пакет фоновых процессов (DBMS_JOBS, DBMS_SCHEDULER), типа cron в unix или OpenEdge Managment jobs.
В прогрессе так же -- придется делать через вторичный процесс, но руками. Это может быть AppServer как написал Юра или любой другой процесс, отличный первоначального.
В одном процессе то что вы хотите мне кажется сделать не удастся.

Предполагаю, что это возможно только скриптом, запустить процедуры под разними пользователями.
