  1 CSESION - session administration
  
  Addition to CSESION on page 49 in the manual:
  
  the macro CSESION has a new operand:
  
  GENKPR = <var: bit:1> |
           *ALLOWED |
           *NOTALLOWED |
           default: *ALLOWED
  
  GENKPR    regulates whether the macro call CGENKPR in this
            session is permitted.
  
     = *ALLOWED
            all calls of this session are assigned to a process on the
            openCRYPT-BOX, that performs operations which may take a 
            long time (CGENKPR).  
  
     = *NOTALLOWED
            all calls of this session are assigned to a process on the
            openCRYPT-BOX, that performs operations which last only a
            short time.  
  
  2 Limitations of the number of sessions per user
  
  Addition to functions on page 28, CSESION on page 49 and to the
  returncode session_count on Page 112 in the manual:
  
  The number of sessions that simultaneously can be opened by a BS2000
  user, is limited. Starting with OSD V6.0, it is possible to define
  the upper limit with the command ADD-USER, and/or 
  MODIFY-USER-ATTRIBUTE with the operand CRYPTO-SESSION-LIMIT. You find
  further information to these commands in the user manual SECOS V5.0
  Security Control system, and/or BS2000/OSD-BC V6.0 commands.  
  
  In versions <OSD V6.0 128 parallel sessions per task are possible.
  If the maximal number of parallel sessions is exceeded, this is
  indicated with the returncode session_count. 
  
  3 new returncode CRYPT_down
  
  The new returncode CRYPT_down is reported if between two function
  calls the subsystem CRYPT was shut down. The cryptographic
  sessions have to be reopened.
