TAKE command

The TAKE command processes a TOPS-20 command file.


Format

     @TAKE (COMMANDS FROM) filespec,
     @@subcommand

     where:

     filespec       is the specification of the  file  containing  the
                    commands to be processed.
                         Default file type - .CMD

     @@subcommand   means that after a comma you can type one  of  the
                    following subcommands:

                    ALLOW      tells the current level of TOPS-20, for
                               the  remainder  of the terminal session
                               (not merely the  current  command),  to
                               continue  processing  a command file if
                               it encounters errors.

                    DISALLOW   tells the current level of TOPS-20, for
                               the  remainder  of the terminal session
                               (not merely the  current  command),  to
                               ignore  any  remaining  commands  in  a
                               command file  after  it  encounters  an
                               error in the file.
                                    Default

                    ECHO       tells the  system  to  print  (on  your
                               terminal  or in the specified file) the
                               commands  that  it  carries  out  while
                               executing  the  current  TAKE  command.
                               Ordinarily only  the  output,  if  any,
                               produced by the commands is printed.

                    NO ECHO    tells  the  system  not  to  print  the
                               commands  that  it  carries  out  while
                               executing the current TAKE command.   A
                               final   message   is   sent,   however,
                               indicating  whether  all  the  commands
                               were      executed.       See      also
                               Hints - Suppressing the Final  Message,
                               below.
                                    Default

                    LOG-FILE filespec
                               tells the system  to  save  the  output
                               from  the  current  TAKE command in the
                               specified file.


Output

     The output from a TAKE command consists of the  output  for  each
     command  in the command file you specify as argument, followed by
     the message, End of filespec, that indicates successful execution
     of all the commands in this file.


Characteristics

     Running Programs From a Command File

          If you put commands that run programs  (including  the  PUSH
          command)  into  a  command  file, and these programs ask for
          arguments, you must be ready to type in these  arguments  at
          your  terminal.  Only TOPS-20 commands and command arguments
          can be put into a command file executed by the TAKE command.


Hints

     Suppressing the Final Message

          If you want to suppress the final message (of the form,  End
          of  filespec)  that  indicates  successful  execution  of  a
          command file by TAKE, give a TAKE command with no  arguments
          as the last line of your command file.


Special Cases

     Nested TAKE Commands

          In the case of nested TAKE commands (those given as commands
          within   command  files),  the  destination  for  output  of
          commands given in an inner command file will default to that
          specified or assumed for the output of commands given in the
          nearest surrounding command file.


Effect on Memory and Terminal

     The TAKE command affects memory and your  terminal  according  to
     the commands stored in the command file you specify as argument.

Examples

     1.  Process a command file.

         @TAKE BACKUP.CMD
          End of BACKUP.CMD.1

     2.  Type a command file that reports system statistics, then give
         the  TAKE  command  with  this filename as argument; send the
         output to the line printer.  Check for this listing as it  is
         being printed.
