1 DUMPER
! DUMPER.HLP -- Created by RUNOFF 08 Dec 81 07:00:05
!
This program reads magtapes written by the DEC-10 BACKUP
program or by the DEC-20 DUMPER program. It allows the user to
select a subset of the files on the tape and to copy them into
selected directories. This program is still under development.
Please report all errors with the MAIL program to SYSTEM.
Usage:
$ MOUNT MTA0:/FOR ! To mount your magtape
$ R KCL:DUMPER ! To run the program, type HELP for help.
2 BASIC-COMMANDS
The following list of commands are used in DUMPER:
USE tape-name
To select the tape drive (eg MTA0:)
RESTORE vaxdir=files
To indicate which files to copy from the tape and the VAX
directory to copy them to. An asterisk may be used for a
wild-card in the file specification. For DEC-10 PPN's, an
underscore (_) is used in place of the first comma. (EG.
[MYDIR]=[11_11]TEXT.DAT or []=[11_11,SUB]*.*) This can be
repeated up to 200 times. For interchange mode tapes, use [*]
as the directory name since no directory name is saved for the
files. For DEC-20 filenames using a minus sign (-), use
underscore instead.
WHAT
To list the RESTORE commands selected
RESET
To reset the list of RESTORE commands.
GO n
This command starts the processing of the tape. The number 'n'
is optional and designates the number of save sets to process.
The program will stop automatically at the logical end of tape,
or for any I/O errors.
EXIT, STOP, or QUIT
To stop the program.
2 TAPE-COMMANDS
REWIND
This command will rewind the tape selected by the USE command.
EOT
This command will move the tape to the 'End of Tape' position.
SKIP n
This command will move the tape over 'n' save sets. If 'n' is
zero, it will move to the beginning of the current save set.
If 'n' is negative, it will move towards the beginning of the
tape.
2 MODE-COMMANDS
LIST
To make a directory listing while processing the tape, enter
this command and then specify the file to receive the listing.
If no filename is specified, the directory listing file is not
created.
FILES
This command will cause the files being created to be printed
on the user's terminal.
SILENT
This command will stop printing the names of files created on
the user's terminal.
ASCII
To do the processing for converting 7-bit ASCII data into VAX
8-bit ASCII data. Currently, the record size is always 64.
BINARY
To do the processing for converting 36-bit data into 5 8-bit
bytes of BINARY data. The least signifigant byte is first and
the most signifigant 4 bits of the 5th byte are zero. The
record size is 640 (1 DEC-10 disk block).
2 Features
There are some 'features' which have not been fixed completely.
These include:
1. Handling text files. Currently it is necessary to use the
TECO text editor to convert the output of DUMPER into a form
that other programs will accept. The command:
$ TECO xxx.dat
*EX$$
will perform the conversion.
2. Output record mode setting is available but is not
currently in a useful form. The record mode selected (NONE,
CR, or FORTRAN) is set in the output file, but the record size
is still 64 for ASCII files, and 640 for BINARY files.
