RTL Routines, PPL$, PPL$INCREMENT_SEMAPHORE
 *Conan The Librarian 

    The Increment a Semaphore routine increments the value of the
    semaphore by 1, analogous to the signal protocol. If any other
    participants are blocked on a call to PPL$DECREMENT_SEMAPHORE for
    this semaphore, one is removed from the queue and awakened. The
    semaphore must have been created by PPL$CREATE_SEMAPHORE.

    Format

      PPL$INCREMENT_SEMAPHORE  semaphore-id
