  18.      _vvvv_ssss_eeee_mmmm_aaaa performs a "V" semaphore operation on the semaphore pointed to by
  19.      _s_e_m_a_p. The value associated with the semaphore is incremented by 1. If
  20.      the semaphore value is then less than or equal to 0, a sleeping process
  21.      is awakened.
  22.  
  23.      _vvvv_ssss_eeee_mmmm_aaaa expects a pointer to the semaphore as its argument. To allocate or
  24.      initialize semaphores, use _iiii_nnnn_iiii_tttt_nnnn_ssss_eeee_mmmm_aaaa(D3X).
