CMSTAPE

NAME

SYNOPSIS

DESCRIPTION

-t

(default) type tape directory of tape file.

-v

verbose

-c

create a CMS tape dump.

-r

append to a CMS tape dump ('r' is non-mnemonic but matches tar).

-x

extract files from tape. If no names given all are extracted. otherwise only those named are extracted. Syntax for names is: fn.ft.

-f

tape is in readtape(1) format: each file block is preceded by a two byte block length with vax byte ordering. If ommitted, /dev/nrmt8 is used.

-i

image (no EBCDIC/ASCII translation or tacking on of newlines). Handled differently under UNIX and CMS: Under UNIX, V-format files are extracted with a halfword length header preceding each record. This makes image extracts and creates a reversible process for V as well as F format files under UNIX. Under CMS, V-format files are written to the CMS filesystem which maintains the record length information, so no length headers are needed in the data.

-u

don't convert filenames to lowercase and vice-versa. By default, lowercase UNIX names become uppercase CMS names and vice-versa.

-d

debug (multiple occurences increase volume of output).

Cmstape reads and writes either a tape device or a file that has been read off a tape by readtape(l). (That is, a file that contains a 2 byte vax order tape block size before each data block). This allows you to get the files off a tape with readtape(l) and transfer them over the network to the system where they will actually be extracted. You can also do the opposite: create a tape dump file, transfer it over the network, and write it to a tape device with writetape(l).

When writing a tape dump under UNIX, file names preceded by -Fnn cause those files to be written in fixed instead of the default variable format. If nn is specified, it will be used for the record length, otherwise 80 is assumed. Under CMS, this switch is ignored; the actual record length and format maintained by the filesystem are used.

Extract all files from a CMS tape:

    % cmstape -x

Create a CMS tape dump on your UNIX system to give to your poor friend forced to use CMS:

    % cmstape -c /dev/nrmt8 cmstape.c -F foo.assemble

Read a CMS tape dump on your UNIX system, send it over the network to your CMS system and extract the files there:

    % readtape
    Reading from /dev/nrmt0
    Writing to file1    123456 bytes.
    Writing to file2         0 bytes.
    % telnet ibmhost
    ftp vaxhost
    ...
    ftp> type i
    ftp> get file1 file1.file
    ftp> quit
    cmstape -xfi file1
