ENABLE command

The ENABLE command enables any special capabilities you may have.


Format

     @ENABLE (CAPABILITIES)
     $


Characteristics

     Dollar Sign Prompt

          The ENABLE command causes the system to print a dollar  sign
          prompt ($), indicating enabled capabilities, in place of the
          standard at sign prompt (@).   The  dollar  sign  prompt  is
          printed  after  ENABLE even if you have not been granted any
          capabilities.

     Capabilities of Log-In Directory Only

          The ENABLE command activates only  those  capabilities  that
          have  been  granted  to  the owner of your log-in directory.
          You do not receive any capabilities as a result  of  CONNECT
          or ACCESS commands or group memberships.


Hints

     Displaying Capabilities

          Capabilities are defined by your login directory but  are  a
          characteristic  of  your  job  and  can  be  enabled  in any
          directory to which you connect.  To list your  capabilities,
          give  the  INFORMATION  DIRECTORY  command  for  your  login
          directory.

     More Information

          Capabilities are assigned with the BUILD command.   See  the
          BUILD   command   subcommands   in  this  manual  for  brief
          descriptions of special capabilities.


Special Cases

     Dollar Sign Prompt in Batch Jobs

          Because a dollar sign placed in the location  of  a  TOPS-20
          prompt  could  be  confused with a batch command, the system
          precedes the enabled prompt with a space for batch jobs.

     Capabilities Changed While Logged In

          Capabilities are given to your job when you log in.  If your
          capabilities  are  changed while you are logged-in, you must
          log out and log in again for the change to take effect.


Warning

     Disabling Capabilities Promptly

          Because your commands are much more  powerful  if  you  have
          capabilities enabled, you should disable them as soon as you
          have finished using them.  Otherwise you or a  program  that
          you run could accidentally damage the system.

     the login directory)          have been granted to you.


Examples

     1.  Enable your capabilities.

         @ENABLE
         $

     2.  Try to assign a tape drive to your job before taking  it  off
         line  for  repairs.   But  it  is already assigned to another
         user, whose terminal is set to  refuse  links.   Enable  your
         capabilities  and  ask  him to deassign the tape drive.  Then
         disable capabilities.

         @ASSIGN MTA2:
         ?MTA2: Already assigned to job 29
         @SYSTAT 29
           29      53   EXEC    R.SCHNEIDER
         @TALK R.SCHNEIDER
         ?Refused, send mail to the user instead
         @ENABLE
