| @@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.
