                     12: mmssggss selects  and displays messages that are  intended to be read
                     13: by all  COHERENT users.  Messages  are mailed to  the login mmssggss.
                     14: They should  contain information  meant to  be read once  by most
                     15: users of the system.
                     16: 
                     17: The command msgs normally is in  a user's .pprrooffiillee, so that it is
                     18: executed every  time he  logs in.   When invoked, it  prompts the
                     19: user with the identifier of the user who sent the message and the
                     20: message's size.  msgs then asks the  user if he wishes to see the
                     21: rest  of the  message.  The  user  should reply  with one  of the
                     22: following:
                     23: 
                     24: 
                     25:          yy          Display the message.
                     26:          <rreettuurrnn>   Display the message.
                     27:          nn          Skip this message and go to the next one.
                     28:          -          Redisplay the last message.
                     29:          qq          Quit mmssggss.
                     30:          _n_u_m_b_e_r     Display message _n_u_m_b_e_r; then continue.
                     31: 
                     32: 
                     33: If environmental  variable PAGER  is defined, msgs  will ``pipe''
                     34: each  message through  the command specified  in PAGER.   For ex-
                     35: ample, the .pprrooffiillee command line:
                     36: 
                     37: 
                     38:     export PAGER="exec /bin/scat -1"
                     39: 
                     40: 
                     41: would invoke /bin/scat for each message with the command line ar-
                     42: gument -1 (the digit one).
                     43: 
                     44: mmssggss writes into the  file $(HHOOMMEE)/.mmssggssrrcc the number of the next
                     45: message the  user will see when he invokes  mmssggss.  mmssggss keeps all
                     46: messages in the directory /uussrr/mmssggss; each message is named with a
                     47: sequential number, which  indicates its message number.  The file
                     48: /uussrr/mmssggss/bboouunnddss contains  the low and  high numbers of  the mes-
                     49: sages in  the directory; mmssggss  determines whether a  user has not
                     50: read a  message by  comparing the information  in $(HHOOMMEE)/.mmssggssrrcc
                     51: with   that   in    /uussrr/mmssggss/bboouunnddss.    If   the   contents   of
                     52: /uussrr/mmssggss/bboouunnddss  are  incorrect, the  problem  can  be fixed  by
                     53: removing that  file; mmssggss will create a new  bboouunnddss file the next
                     54: time it is run.
                     55: 
                     56: When  the contents  of  a message  are no  longer needed,  simply
                     57: remove  that message.   Avoid removing  the  bboouunnddss file  and the
                     58: highest numbered message at the same time.
                     59:

                     75:      command mmssggss -qq is often used in profile scripts.

                     78:      Start at message  _n_u_m_b_e_r rather than at the message recorded
                     79:      in $(HHOOMMEE)/.mmssggssrrcc.   If _n_u_m_b_e_r  is greater than  zero, then
                     80:      start with  that message; if _n_u_m_b_e_r is  less than zero, then
                     81:      begin   _n_u_m_b_e_r   messages  before   the   one  recorded   in
                     82:      $(HHOOMMEE)/.mmssggssrrcc.
