Maybe 12.4.4.1 should remove the semcls.cls code and only hint that an ooRexx sample implementation of semaphores can be found in the samples directory. Instead references to the new classes EventSemaphore and MutexSemaphore should be supplied such that a link gets established. This has the advantage that the user can also study the examples there that take advantage of the semaphores. If no one objects I will change 12.4.4.1 accordingly. ---rony
