1 CB
 Allows you to communicate with any other user that is currently logged
 in to VAX/VMS, regardless of terminal type.

 Format:

       CB

2 Handles
 Your "handle" is the name by which you are known while running CB/Vax.
 While there aren't any rules for choosing handles we recommend that,
 when you are engaged in serious conversation, you use your real name.
 Your handle is remembered for your entire timesharing session, even if
 you exit CB/Vax and re-enter it.  This is done by defining a global
 symbol which you may want to do in your LOGIN.COM file.  Insert a line
 of the form

       $ CB_HANDLE :== "your handle"

 Then, you will never be asked for your handle.  You can change your handle
 while in CB/Vax by using the /HAN command.

2 Commands
 All CB/Vax commands are typed while in the program, and are prefaced by
 a slash (/).  Only enough of each command to distinguish it from any
 other command need be typed.

2 Channels
 CB/Vax offers 40 channels on which separate conversations may be held
 simultaneously.  When you enter the program, you are placed on channel
 1.  Use the /TUN command to change your channel.

2 /EXIT
 Performs an orderly exit from CB/Vax.  Control-Z will also perform this
 function.  Note that control-C and control-Y will NOT exit from the utility.

2 /HANDLE
 Allows you to change your handle while running CB/Vax.

 Format:
        /HANdle new-handle

 If you do not supply a new handle, you will be prompted for it.  Your
 handle can not match any handle that is currently running CB/Vax.
 Choosing an invalid handle will not change your current handle.

2 /HELP
  Prints a short summary of CB/Vax commands.

2 /MONITOR
  Allows you to "listen" to another channel in addition to the one to which
  you are tuned.

  Format:
         /MONitor n

  The channel n may be from 1 to 40.  To cease monitoring of a channel,
  use the /UNMONITOR command.  You may monitor up to 2 additional channels.

2 /SCRAMBLE
  Allows your transmissions to only be read by other 'scrambled' users.

  Format:
         /SCRamble key

  The scramble key must be supplied.  This key instructs CB to send your
  messages using this key.  Only CB users who have entered the same key
  will be able to recieve your messages.  Using the /SCR, you will only
  recieve messages scrambled with the same key.
        See also /SMC, /UNS, &  /XCL

2 /SMC
  (Scramble and Monitor Clear)
  Allows you to scramble your transmissions but still recieve unscrambled
  transmissions.

  Format:
         /SMC key

  This command is identical to scramble except it allows you to recieve
  both scrambled and unscrambled transmissions.

        See also /SCR, /UNS, & /XCL

2 /SQUELCH
  Allows you to "tune out" a user.

  Format:
         /SQUelch handle

  The handle to squelch must be supplied.  Only 1 user may be squelched at
  a time.

2 /STATUS
 Prints a brief list of activity on each of the 40 CB/Vax channels.  Each
 item is of the form "(n)p", where "n" is the channel number and "p" is
 the number of people on that channel.  Additionally, a "#" is displayed
 following the channel to which you are currently tuned and an * is
 displayed on any channel which you are monitoring.

2 /SUMMON
 Calls another user and requests that the user also run CB/Vax.  The
 user will get a message of the form

        handle(user) requests your presence on CB.

 where "handle" is your current handle, and "user" is your username.
 All users logged in to the specified username will be summoned.  Note
 that this message is issued only once per command and does not repeat
 like the PHONE command.

 Format:

        /SUMMON username
2 /TIME
  Report current time, day, and date.

2 /TUNE
 Changes your CB/Vax channel.  Channels 1-40 are defined.

 Format:

 where "n" is the new channel number.

2 /UNMONITOR
  Stop monitoring a channel.

  Format:
         /UNMonitor n

2 /UNSCRAMBLE
  Turns off all scrambling options.

       See also /SCR, /SMC, /XCL
2 /USTAT

 each user's terminal, UIC, channel, and handle.
2 /XCL
  (Xmit in Clear)
  Allows you to recieve scrambled transmissions while sending in clear.

  Format:

  or scrambled by the appropriate key.  Your transmissions will be in clear.
